I believe in soft-determinism, but I also have an understanding for hard-determinism.
Soft-determinism basically states that one's future depends upon their current actions. I believe that we, in fact, have free will and are able to make our own decisions. Yet, there are cases that make me believe that some people simply lack the mentality to make their own decisions; mental handicaps being the prime example. This is what also has me leaning towards hard-determinism.
In a nutshell: Hard-determinism constitutes that events are predetermined. I'm not going to get into that either
I honestly believe in libertarianism, but I'm not getting into that with a few people on this site.
Basically, I believe in free will.
