Beyond determinism and materialism, or isn't it time we took consciousness seriously?

This essay argues: (1) that the fundamental conflict between the behaviorist and cognitive approaches to psychology are philosophical, not scientific; (2) that the philosophical premises underlying behaviorism (materialism, epiphenomenalism, functional model of causality, and the rejection of concepts referring to conscious states and processes) are false; and (3) that an objective, scientific approach to psychology must take consciousness and volition as axiomatic starting points.
