1630s, “a class of considerations from which probable arguments can be drawn,” singular form of “Topics” (1560s), the name of a work by Aristotle on logical and rhetorical generalities, from Latin Topica, from Greek Ta Topika, literally “matters concerning topoi,” “commonplaces,” neuter plural of noun use of topikos “pertaining to a common place, of a place, local,” from topos “place” (see topos). The meaning “matter treated in speech or writing, subject, theme” is first recorded 1720.
Evolutionary developmental biology (informally, evo-devo) is a field of biological research that compares the developmental processes of different organisms to infer the ancestral relationships between them and how developmental processes evolved.
The field grew from 19th-century beginnings, where embryology faced a mystery: zoologists did not know how embryonic development was controlled at the molecular level. Charles Darwin noted that having similar embryos implied common ancestry, but little progress was made until the 1970s. Then, recombinant DNA technology at last brought embryology together with molecular genetics. A key early discovery was of homeotic genes that regulate development in a wide range of eukaryotes.
The field is characterised by some key concepts, which took evolutionary biologists by surprise. One is deep homology, the finding that dissimilar organs such as the eyes of insects, vertebrates and cephalopod molluscs, long thought to have evolved separately, are controlled by similar genes such as pax-6, from the evo-devo gene toolkit. These genes are ancient, being highly conserved among phyla; they generate the patterns in time and space which shape the embryo, and ultimately form the body plan of the organism. Another is that species do not differ much in their structural genes, such as those coding for enzymes; what does differ is the way that gene expression is regulated by the toolkit genes. These genes are reused, unchanged, many times in different parts of the embryo and at different stages of development, forming a complex cascade of control, switching other regulatory genes as well as structural genes on and off in a precise pattern. This multiple pleiotropic reuse explains why these genes are highly conserved, as any change would have many adverse consequences which natural selection would oppose.
New morphological features and ultimately new species are produced by variations in the toolkit, either when genes are expressed in a new pattern, or when toolkit genes acquire additional functions. Another possibility is the Neo-Lamarckian theory that epigenetic changes are later consolidated at gene level, something that may have been important early in the history of multicellular life.
Bias is disproportionate weight in favor of or against one thing, person, or group compared with another, usually in a way considered to be unfair.
Biases can be learned by watching cultural contexts. People may develop biases toward or against an individual, an ethnic group, a sexual or gender identity, a nation, a religion, a social class, a political party, theoretical paradigms and ideologies within academic domains, or a species. Biased means one-sided, lacking a neutral viewpoint, or not having an open mind. Bias can come in many forms and is related to prejudice and intuition.
In science and engineering, a bias is a systematic error. Statistical bias results from an unfair sampling of a population, or from an estimation process that does not give accurate results on average.
Academic freedom is the conviction that the freedom of inquiry by faculty members is essential to the mission of the academy as well as the principles of academia, and that scholars should have freedom to teach or communicate ideas or facts (including those that are inconvenient to external political groups or to authorities) without being targeted for repression, job loss, or imprisonment.
Academic freedom is a contested issue and, therefore, has limitations in practice. In the United States, for example, according to the widely recognized “1940 Statement on Academic Freedom and Tenure” of the American Association of University Professors, teachers should be careful to avoid controversial matter that is unrelated to the subject. When they speak or write in public, they are free to express their opinions without fear from institutional censorship or discipline, but they should show restraint and clearly indicate that they are not speaking for their institution. Academic tenure protects academic freedom by ensuring that teachers can be fired only for causes such as gross professional incompetence or behavior that evokes condemnation from the academic community itself.
Louis Albert Necker de Saussure HFRSE MWS FGS (April 10, 1786 – November 20, 1861) was a Swiss crystallographer and geographer.
He is best remembered for devising the optical illusion now known as the Necker cube.
He was born in the Republic of Geneva, the son of botanist Professor Jacques Necker, nephew and namesake of statesman Jacques Necker, and Albertine Necker de Saussure.
He was educated in Geneva, then sent to Edinburgh University in Scotland to study Sciences from 1806 to 1808.
He returned to Scotland in 1841 and settled on the Isle of Skye, lodging with the Cameron family at Bosville Terrace in Portree. His scientific interests turned to astronomy and a study of the aurora borealis. In 1843 and 1845, he was joined by his friend, James Forbes, a glaciologist. Together, they made the first accurate map of the Cuillins.
He spent his later life mountaineering and collecting ornithological specimens. He died in Portree on 20 November 1861. He is buried next to the Cameron family in the Portree churchyard.[8
DeepDream is a computer vision program created by Google engineer Alexander Mordvintsev which uses a convolutional neural network to find and enhance patterns in images via algorithmic pareidolia, thus creating a dream-like hallucinogenic appearance in the deliberately over-processed images.
Google’s program popularized the term (deep) “dreaming” to refer to the generation of images that produce desired activations in a trained deep network, and the term now refers to a collection of related approaches.
The DeepDream software originated in a deep convolutional network codenamed “Inception” after the film of the same name, was developed for the ImageNet Large-Scale Visual Recognition Challenge (ILSVRC) in 2014 and released in July 2015.
The dreaming idea and name became popular on the internet in 2015 thanks to Google’s DeepDream program. The idea dates from early in the history of neural networks, and similar methods have been used to synthesize visual textures. Related visualization ideas were developed (prior to Google’s work) by several research groups.
After Google published their techniques and made their code open source, a number of tools in the form of web services, mobile applications, and desktop software appeared on the market to enable users to transform their own photos.
Mindfulness is the psychological process of bringing one’s attention to experiences occurring in the present moment, which one can develop through the practice of meditation and through other training. Mindfulness is derived from sati, a significant element of Buddhist traditions, and based on Zen, Vipassanā, and Tibetan meditation techniques.1 Individuals who have contributed to the popularity of mindfulness in the modern Western context include Thích Nhất Hạnh (1926– ), Herbert Benson (1935– ), Jon Kabat-Zinn (1944– ), and Richard J. Davidson (1951– ).
Clinical psychology and psychiatry since the 1970s have developed a number of therapeutic applications based on mindfulness for helping people experiencing a variety of psychological conditions. Mindfulness practice has been employed to reduce symptoms of depression, to reduce stress, anxiety, and in the treatment of drug addiction. Programs based on Kabat-Zinn’s and similar models have been adopted in schools, prisons, hospitals, veterans’ centers, and other environments, and mindfulness programs have been applied for additional outcomes such as for healthy aging, weight management, athletic performance, helping children with special needs, and as an intervention during the perinatal period.
Clinical studies have documented both physical- and mental-health benefits of mindfulness in different patient categories as well as in healthy adults and children. Research studies have consistently shown a positive relationship between trait mindfulness and psychological health. The practice of mindfulness appears to provide therapeutic benefits to people with psychiatric disorders, including to those with psychosis. Studies also indicate that rumination and worry contribute to the onset of a variety of mental disorders, and that mindfulness-based interventions significantly reduce both rumination and worry. Further, the practice of mindfulness may be a preventive strategy to halt the development of mental-health problems.
The necessity for more high-quality research in this field has also been identified – such as the need for more randomized controlled studies, for providing more methodological details in reported studies and for the use of larger sample sizes.
Memetics (also referred to colloquially as memeology) is the study of information and culture based on an analogy with Darwinian evolution. Proponents describe memetics as an approach to evolutionary models of cultural information transfer. Critics regard memetics as a pseudoscience. Memetics describes how an idea can propagate successfully, but doesn’t necessarily imply a concept is factual.
The term meme was coined in Richard Dawkins‘ 1976 book The Selfish Gene, but Dawkins later distanced himself from the resulting field of study. Analogous to a gene, the meme was conceived as a “unit of culture” (an idea, belief, pattern of behaviour, etc.) which is “hosted” in the minds of one or more individuals, and which can reproduce itself in the sense of jumping from the mind of one person to the mind of another. Thus what would otherwise be regarded as one individual influencing another to adopt a belief is seen as an idea-replicator reproducing itself in a new host. As with genetics, particularly under a Dawkinsian interpretation, a meme’s success may be due to its contribution to the effectiveness of its host.
The Usenet newsgroup alt.memetics started in 1993 with peak posting years in the mid to late 1990s. The Journal of Memetics was published electronically from 1997 to 2005.
In his book The Selfish Gene (1976), the evolutionary biologist Richard Dawkins used the term meme to describe a unit of human cultural transmission analogous to the gene, arguing that replication also happens in culture, albeit in a different sense. Bella Hiscock outlined a similar hypothesis in 1975, which Dawkins referenced. Cultural evolution itself is a much older topic, with a history that dates back at least as far as Darwin‘s era.
Dawkins (1976) proposed that the meme is a unit of information residing in the brain and is the mutating replicator in human cultural evolution. It is a pattern that can influence its surroundings – that is, it has causal agency – and can propagate. This proposal resulted in debate among sociologists, biologists, and scientists of other disciplines. Dawkins himself did not provide a sufficient explanation of how the replication of units of information in the brain controls human behaviour and ultimately culture, and the principal topic of the book was genetics. Dawkins apparently did not intend to present a comprehensive theory of memetics in The Selfish Gene, but rather coined the term meme in a speculative spirit. Accordingly, different researchers came to define the term “unit of information” in different ways.
The modern memetics movement dates from the mid-1980s. A January 1983 “Metamagical Themas” column by Douglas Hofstadter, in Scientific American, was influential – as was his 1985 book of the same name. “Memeticist” was coined as analogous to “geneticist” – originally in The Selfish Gene. Later Arel Lucas suggested that the discipline that studies memes and their connections to human and other carriers of them be known as “memetics” by analogy with “genetics”. Dawkins’ The Selfish Gene has been a factor in attracting the attention of people of disparate intellectual backgrounds. Another stimulus was the publication in 1991 of Consciousness Explained by Tufts University philosopher Daniel Dennett, which incorporated the meme concept into a theory of the mind. In his 1991 essay “Viruses of the Mind“, Richard Dawkins used memetics to explain the phenomenon of religious belief and the various characteristics of organised religions. By then, memetics had also become a theme appearing in fiction (e.g. Neal Stephenson’s Snow Crash).
The idea of language as a virus had already been introduced by William S. Burroughs as early as 1962 in his book The Ticket That Exploded, and later in The Electronic Revolution, published in 1970 in The Job. Douglas Rushkoff explored the same concept in Media Virus: Hidden Agendas in Popular Culture in 1995.
However, the foundation of memetics in its full modern incarnation originated in the publication in 1996 of two books by authors outside the academic mainstream: Virus of the Mind: The New Science of the Meme by former Microsoft executive turned motivational speaker and professional poker-player, Richard Brodie, and Thought Contagion: How Belief Spreads Through Society by Aaron Lynch, a mathematician and philosopher who worked for many years as an engineer at Fermilab. Lynch claimed to have conceived his theory totally independently of any contact with academics in the cultural evolutionary sphere, and apparently was not even aware of Dawkins’ The Selfish Gene until his book was very close to publication.
Around the same time as the publication of the books by Lynch and Brodie the e-journal Journal of Memetics – Evolutionary Models of Information Transmission appeared on the web. It was first hosted by the Centre for Policy Modelling at Manchester Metropolitan University but later taken over by Francis Heylighen of the CLEA research institute at the Vrije Universiteit Brussel. The e-journal soon became the central point for publication and debate within the nascent memeticist community. (There had been a short-lived paper-based memetics publication starting in 1990, the Journal of Ideas edited by Elan Moritz.) In 1999, Susan Blackmore, a psychologist at the University of the West of England, published The Meme Machine, which more fully worked out the ideas of Dennett, Lynch, and Brodie and attempted to compare and contrast them with various approaches from the cultural evolutionary mainstream, as well as providing novel, and controversial, memetics-based theories for the evolution of language and the human sense of individual selfhood.
The term “meme”
The term “meme” derives from the Ancient Greek μιμητής (mimētḗs), meaning “imitator, pretender”. The similar term “mneme” was used in 1904, by the German evolutionary biologist Richard Semon, best known for his development of the engram theory of memory, in his work Die mnemischen Empfindungen in ihren Beziehungen zu den Originalempfindungen, translated into English in 1921 as The Mneme. Until Daniel Schacter published Forgotten Ideas, Neglected Pioneers: Richard Semon and the Story of Memory in 2000, Semon’s work had little influence, though it was quoted extensively in Erwin Schrödinger’s prescient 1956 Tarner Lecture “Mind and Matter”. Richard Dawkins (1976) apparently coined the word “meme” independently of Semon, writing this:
“‘Mimeme’ comes from a suitable Greek root, but I want a monosyllable that sounds a bit like ‘gene’. I hope my classicist friends will forgive me if I abbreviate mimeme to meme. If it is any consolation, it could alternatively be thought of as being related to ‘memory’, or to the French word même.”
In 2005, the Journal of Memetics – Evolutionary Models of Information Transmission ceased publication and published a set of articles on the future of memetics. The website states that although “there was to be a relaunch…after several years nothing has happened”. Susan Blackmore has left the University of the West of England to become a freelance science-writer and now concentrates more on the field of consciousness and cognitive science. Derek Gatherer moved to work as a computer programmer in the pharmaceutical industry, although he still occasionally publishes on memetics-related matters. Richard Brodie is now climbing the world professional poker rankings. Aaron Lynch disowned the memetics community and the words “meme” and “memetics” (without disowning the ideas in his book), adopting the self-description “thought contagionist”. He died in 2005.
Susan Blackmore (2002) re-stated the definition of meme as: whatever is copied from one person to another person, whether habits, skills, songs, stories, or any other kind of information. Further she said that memes, like genes, are replicators in the sense as defined by Dawkins. That is, they are information that is copied. Memes are copied by imitation, teaching and other methods. The copies are not perfect: memes are copied with variation; moreover, they compete for space in our memories and for the chance to be copied again. Only some of the variants can survive. The combination of these three elements (copies; variation; competition for survival) forms precisely the condition for Darwinian evolution, and so memes (and hence human cultures) evolve. Large groups of memes that are copied and passed on together are called co-adapted meme complexes, or memeplexes. In Blackmore’s definition, the way that a meme replicates is through imitation. This requires brain capacity to generally imitate a model or selectively imitate the model. Since the process of social learning varies from one person to another, the imitation process cannot be said to be completely imitated. The sameness of an idea may be expressed with different memes supporting it. This is to say that the mutation rate in memetic evolution is extremely high, and mutations are even possible within each and every iteration of the imitation process. It becomes very interesting when we see that a social system composed of a complex network of microinteractions exists, but at the macro level an order emerges to create culture.
Internalists and externalists
The memetics movement split almost immediately into two. The first group were those who wanted to stick to Dawkins’ definition of a meme as “a unit of cultural transmission“. Gibron Burchett, another memeticist responsible for helping to research and co-coin the term memetic engineering, along with Leveious Rolando and Larry Lottman, has stated that a meme can be defined, more precisely, as “a unit of cultural information that can be copied, located in the brain”. This thinking is more in line with Dawkins’ second definition of the meme in his book The Extended Phenotype. The second group wants to redefine memes as observable cultural artifacts and behaviors. However, in contrast to those two positions, Blackmore does not reject either concept of external or internal memes.
These two schools became known as the “internalists” and the “externalists.” Prominent internalists included both Lynch and Brodie; the most vocal externalists included Derek Gatherer, a geneticist from Liverpool John Moores University, and William Benzon, a writer on cultural evolution and music. The main rationale for externalism was that internal brain entities are not observable, and memetics cannot advance as a science, especially a quantitative science, unless it moves its emphasis onto the directly quantifiable aspects of culture. Internalists countered with various arguments: that brain states will eventually be directly observable with advanced technology, that most cultural anthropologists agree that culture is about beliefs and not artifacts, or that artifacts cannot be replicators in the same sense as mental entities (or DNA) are replicators. The debate became so heated that a 1998 Symposium on Memetics, organised as part of the 15th International Conference on Cybernetics, passed a motion calling for an end to definitional debates. McNamara demonstrated in 2011 that functional connectivity profiling using neuroimaging tools enables the observation of the processing of internal memes, “i-memes”, in response to external “e-memes”.
An advanced statement of the internalist school came in 2002 with the publication of The Electric Meme, by Robert Aunger, an anthropologist from the University of Cambridge. Aunger also organised a conference in Cambridge in 1999, at which prominent sociologists and anthropologists were able to give their assessment of the progress made in memetics to that date. This resulted in the publication of Darwinizing Culture: The Status of Memetics as a Science, edited by Aunger and with a foreword by Dennett, in 2001.
Research methodologies that apply memetics go by many names: Viral marketing, cultural evolution, the history of ideas, social analytics, and more. Many of these applications do not make reference to the literature on memes directly but are built upon the evolutionary lens of idea propagation that treats semantic units of culture as self-replicating and mutating patterns of information that are assumed to be relevant for scientific study. For example, the field of public relations is filled with attempts to introduce new ideas and alter social discourse. One means of doing this is to design a meme and deploy it through various media channels. One historic example of applied memetics is the PR campaign conducted in 1991 as part of the build-up to the first Gulf War in the United States.
The application of memetics to a difficult complex social system problem, environmental sustainability, has recently been attempted at thwink.org Using meme types and memetic infection in several stock and flow simulation models, Jack Harich has demonstrated several interesting phenomena that are best, and perhaps only, explained by memes. One model, The Dueling Loops of the Political Powerplace, argues that the fundamental reason corruption is the norm in politics is due to an inherent structural advantage of one feedback loop pitted against another. Another model, The Memetic Evolution of Solutions to Difficult Problems, uses memes, the evolutionary algorithm, and the scientific method to show how complex solutions evolve over time and how that process can be improved. The insights gained from these models are being used to engineer memetic solution elements to the sustainability problem.
Another application of memetics in the sustainability space is the crowdfunded Climate Meme Project conducted by Joe Brewer and Balazs Laszlo Karafiath in the spring of 2013. This study was based on a collection of 1000 unique text-based expressions gathered from Twitter, Facebook, and structured interviews with climate activists. The major finding was that the global warming meme is not effective at spreading because it causes emotional duress in the minds of people who learn about it. Five central tensions were revealed in the discourse about [climate change], each of which represents a resonance point through which dialogue can be engaged. The tensions were Harmony/Disharmony (whether or not humans are part of the natural world), Survival/Extinction (envisioning the future as either apocalyptic collapse of civilization or total extinction of the human race), Cooperation/Conflict (regarding whether or not humanity can come together to solve global problems), Momentum/Hesitation (about whether or not we are making progress at the collective scale to address climate change), and Elitism/Heretic (a general sentiment that each side of the debate considers the experts of its opposition to be untrustworthy).
Ben Cullen, in his book Contagious Ideas, brought the idea of the meme into the discipline of archaeology. He coined the term “Cultural Virus Theory”, and used it to try to anchor archaeological theory in a neo-Darwinian paradigm. Archaeological memetics could assist the application of the meme concept to material culture in particular.
Francis Heylighen of the Center Leo Apostel for Interdisciplinary Studies has postulated what he calls “memetic selection criteria”. These criteria opened the way to a specialized field of applied memetics to find out if these selection criteria could stand the test of quantitative analyses. In 2003 Klaas Chielens carried out these tests in a Masters thesis project on the testability of the selection criteria.
In Selfish Sounds and Linguistic Evolution, Austrian linguist Nikolaus Ritt has attempted to operationalise memetic concepts and use them for the explanation of long term sound changes and change conspiracies in early English. It is argued that a generalised Darwinian framework for handling cultural change can provide explanations where established, speaker centred approaches fail to do so. The book makes comparatively concrete suggestions about the possible material structure of memes, and provides two empirically rich case studies.
Australian academic S.J. Whitty has argued that project management is a memeplex with the language and stories of its practitioners at its core. This radical approach sees a project and its management as an illusion; a human construct about a collection of feelings, expectations, and sensations, which are created, fashioned, and labeled by the human brain. Whitty’s approach requires project managers to consider that the reasons for using project management are not consciously driven to maximize profit, and are encouraged to consider project management as naturally occurring, self-serving, evolving process which shapes organizations for its own purpose.
Swedish political scientist Mikael Sandberg argues against “Lamarckian” interpretations of institutional and technological evolution and studies creative innovation of information technologies in governmental and private organizations in Sweden in the 1990s from a memetic perspective. Comparing the effects of active (“Lamarckian”) IT strategy versus user–producer interactivity (Darwinian co-evolution), evidence from Swedish organizations shows that co-evolutionary interactivity is almost four times as strong a factor behind IT creativity as the “Lamarckian” IT strategy.
