The free will/destiny debate is in my mind, a discussion on the paradox of dichotomies.
It's really pretty simple:
(*) Is a "2" two entities of "1" or one entity of "2"?
(*) Are mind and body seperate or the same?
(*) Is a coin two different objects just because it has two different sides?
These seem like childish questions because they're so elemental.
(*) A "2" is both one number and two (2 = 1+1)
(*) Mind and body are like two sides of a coin
(*) A coin is a single object with two sides that appear to us at different moments in time.
Humans are constantly free and constantly under control.
