The subtlety of sameness: a theory and computer model of analogy-making
1995
International audience; The research described in this book is based on the premise that human analogy-making is an extension of our constant background process of perceiving - in other words, that analogy-making and the perception of sameness are two sides of the same coin. At the heart of the author's theory and computer model of analogy-making is the idea that the building-up and the manipulation of representations are inseparable aspects of mental functioning, in contrast to traditional AI models of high-level cognitive processes, which have almost always depended on a clean separation. A computer program called Tabletop forms analogies in a microdomain consisting of everyday objects on…
Some considerations on Hydra groups and a new bound for the length of words
2014
Abstract After a survey on some recent results of Riley and others on Ackermann functions and Hydra groups, we make an analogy between DNA sequences, whose growth is the same of that of Hydra groups, and a musical piece, written with the same algorithmic criterion. This is mainly an aesthetic observation, which emphasizes the importance of the combinatorics of words in two different contexts. A result of specific mathematical interest is placed at the end, where we sharpen some previous bounds on deterministic finite automata in which there are languages with hairpins.

A module for syntactic processing in music?
2006
Music and language have rules governing the structural organization of events. By analogy to language, these rules are referred to as the ‘syntactic rules’ of music. Does this analogy imply that the brain actually performs syntactic computations on musical structures, similar to those for language and based on a specialized module [1–3]? In contrast to linguistic syntax, which involves abstract computation between words, rules governing musical syntax are rooted in psychoacoustic properties of sound: syntactically related events are related on a sensory level and involve only weak acoustical deviance.
Aristotle’s Doctrine of Causes and the Manipulative Theory of Causality
2018
I will argue for the similarity between some aspects of Aristotle’s doctrine of causes and a particular kind of interventionist theory of causality. The interventionist account hypothesizes that there is a connection between causation and human intervention: the idea of a causal relation between two events is generated by the reflection of human beings on their own operating. This view is remindful of the Aristotelian concept of αἴτιον (cause), which is linked to the figure of the αἴτιος, the person who is responsible of an action. Aristotle conceives of the efficient cause as the active element which, in the φύσις, gives rise to movement and imposes the form, in analogy with the active ele…
The flourishing diversity of models in theoretical morphology: from current practices to future macroevolutionary and bioenvironmental challenges.
2008
17 pages; International audience; For decades, theoretical morphological studies of different groups of organisms have been successfully pursued in biological, paleontological, and computational contexts, often with distinct modeling approaches and research questions. A regular influx of new perspectives and varied expertise has contributed to the emergence of a veritable multidisciplinary outlook for theoretical morphology. The broadening of this discipline is reflected in a substantial increase in the number of models, leading to a bewildering diversity that has yet to be scrutinized. In this work, we tackle this issue in a synthetic fashion, with a quantitativemeta-analysis that allows a…
The Uses of Analogies in Seventeenth and Eighteenth Century Science
2011
The object of this paper is to look at the extent and nature of the uses of analogy during the first century following the so-called scientific revolution.Using the research tool provided by JSTOR we systematically analyze the uses of “analog” and its cognates (analogies, analogous, etc.) in the Philosophical Transactions of the Royal Society of London for the period 1665–1780. In addition to giving the possibility of evaluating quantitatively the proportion of papers explicitly using analogies, this approach makes it possible to go beyond the maybe idiosyncratic cases of Descartes, Kepler, Galileo, and other much studied giants of the so-called Scientific Revolution. As a result a classifi…
The force interpretation of evolutionary theory: scope and limits
2016
La teoría evolutiva suele entenderse como una teoría causal donde las causas principales del cambio evolutivo son identificadas con la selección natural, la deriva genética, la mutación y la migración. Siguiendo este razonamiento, muchos biólogos y filósofos de la biología han estructurado la teoría evolutiva de forma análoga a la mecánica newtoniana, entendiendo la teoría evolutiva como una teoría de fuerzas. El punto clave en el que se sustenta la analogía, es que la estructura de la mecánica newtoniana permite identificar los elementos causales del sistema de interés. De esta manera, la teoría evolutiva encuentra una útil imagen explicativa del fenómeno evolutivo, estructurándose como un…
An immune system model in discrete time based on the analogy with the central nervous system
1988
Jerne's model for the immune system formulated in terms of a neural network recently proposed by Weisbuch and Atlan is generalized to interactions with continuous coupling coefficients. It is shown that even the extended model can be solved analytically without the aid of computer simulations and exhibits one additional attractor, which corresponds to a configuration with high concentrations of active killer cells eventually causing death of the organism.
The development of analogy making in children: cognitive load and executive functions.
2010
The aim of the current study was to investigate the performance of 6-, 8-, and 14-year-olds on an analogy-making task involving analogies in which there are competing perceptual and relational matches. We hypothesized that the selection of the common relational structure requires the inhibition of other salient features, in particular, perceptual matches. Using an A:B::C:D paradigm, we showed that children’s performance in analogy-making tasks depends crucially on the nature of the distractors. Children chose more perceptual distractors having a common feature with C compared with A or B (Experiment 1). In addition, they were also influenced by unstructured random textures. When measuring r…
