Quote by Richard C. Lewontin

“The interpenetration of chance and determination bears on the problem of how there can be a scientific approach to society when individual human behavior and consciousness seem unpredictable. Those who despair to point out that people are not machines, that there are subjective processes in the making of decisions, that it is not 'classes' but individuals who make choices. Terms such as "the human factor" or "subjective factors" with their implication of chance and unpredictability are invoked as the negation of regularity and lawfulness. And indeed it is true that individual behavior and consciousness are the consequences of intersection of a large number of weakly determining factors. But it does not follow that where there is choice, subjectivity, and individuality there cannon also be predictability. The error to take the individual as causally prior to the whole and not to appreciate that the social has causal properties within which individual consciousness and action are formed. While the consciousness of an individual is not determined by his/her class position but is influenced by idiosyncratic factors that appear as random, those random factors operate within a domain and with probabilities that are constrained and directed by social forces.”
