In this first-ever examination of Charles Darwin’s sketches, drawings, and illustrations, Julia Voss presents the history of evolutionary theory told in pictures. Darwin had a life-long interest in pictorial representations of nature, sketching out his evolutionary theory and related ideas for over forty years. Voss details the pictorial history of Darwin’s theory of evolution, starting with his notebook sketches of 1837 and ending with the illustrations in The Expression of Emotions in Man and Animals (1872). These images were profoundly significant for Darwin’s long-term argument for evolutionary theory; each characterizes a different aspect of his relationship with the visual information and constitutes what can be called an “icon” of evolution. Voss shows how Darwin “thought with his eyes” and how his pictorial representations and the development and popularization of the theory of evolution were vitally interconnected.
Voss explores four of Darwin’s images in depth, and weaves about them a story on the development and presentation of Darwin’s theory, in which she also addresses the history of Victorian illustration, the role of images in science, the technologies of production, and the relationship between specimen, words, and images.
Agent_Zero: Toward Neurocognitive Foundations for Generative Social Science [EPUB]

In this pioneering synthesis, Joshua Epstein introduces a new theoretical entity: Agent_Zero. This software individual, or "agent," is endowed with distinct emotional/affective, cognitive/deliberative, and social modules. Grounded in contemporary neuroscience, these internal components interact to generate observed, often far-from-rational, individual behavior. When multiple agents of this new type move and interact spatially, they collectively generate an astonishing range of dynamics spanning the fields of social conflict, psychology, public health, law, network science, and economics.
Epstein weaves a computational tapestry with threads from Plato, Hume, Darwin, Pavlov, Smith, Tolstoy, Marx, James, and Dostoevsky, among others. This transformative synthesis of social philosophy, cognitive neuroscience, and agent-based modeling will fascinate scholars and students of every stripe. Epstein’s computer programs are provided in the book or on its Princeton University Press website, along with movies of his "computational parables."
Agent_Zero is a signal departure in what it includes (e.g., a new synthesis of neurally grounded internal modules), what it eschews (e.g., standard behavioral imitation), the phenomena it generates (from genocide to financial panic), and the modeling arsenal it offers the scientific community.
For generative social science, Agent_Zero presents a groundbreaking vision and the tools to realize it.

Agent-based computational modeling is changing the face of social science. In Generative Social Science, Joshua Epstein argues that this powerful, novel technique permits the social sciences to meet a fundamentally new standard of explanation, in which one "grows" the phenomenon of interest in an artificial society of interacting agents: heterogeneous, boundedly rational actors, represented as mathematical or software objects. After elaborating this notion of generative explanation in a pair of overarching foundational chapters, Epstein illustrates it with examples chosen from such far-flung fields as archaeology, civil conflict, the evolution of norms, epidemiology, retirement economics, spatial games, and organizational adaptation. In elegant chapter preludes, he explains how these widely diverse modeling studies support his sweeping case for generative explanation.
