The Nature of Rationality

Disciplines:
philosophy
philosophy/decision theory

Summary

Robert Nozick's investigation of the nature of rationality — arguing that rationality is not derivable from pure logic but involves evolutionary pressures, symbolic utility, and practical reasoning.

Core Contribution

Evolutionary account of rationality: our rational capacities evolved to track fitness, not truth — rationality must be understood against this background. Symbolic utility: actions have utility beyond their instrumental value — they express and constitute one's identity and commitments. The principle of rational belief: beliefs should track truth but this is not a purely logical constraint.
