You don’t know freedom if you fear death, fear law enforcement, or fear social exile. What we think of as thinking is conditioned by all of these. If you fear any of these I’d question whether it is thinking that you do. It isn’t difficult to surmise why we would have evolved these fears. In some sense we evolved not to think. Heh mistyped it as “evilved” – these fears are the non-theological origins of evil- theology probably adopted “evil” from those.
