In part 1 of this essay, I argued that individual freedom is not only compatible with determinism but dependent on it. I also argued that freedom is not an "either/or" condition. Rather, actions may be more or less free, and therefore, more or less "responsible," depending on a number of contingent factors, yielding various degrees of freedom. Psychiatrists, I suggested, can be most helpful in so far as we can describe, study, and categorize these degrees of freedom and the psychopathological conditions that undermine them. In part 2, I elaborate on the "naturalistic" model of freedom and autonomy and suggest how it may be applied to psychiatric disorders and medico-legal determinations of culpability.
