I have a very simplistic view. Everything is just matter changing form, therefore although there are many possibilities -- past, present, future -- none of them extend beyond the physical realm of action/reaction or cause and effect. We are bound to the physical no matter what, even if our own consciousness makes it seem otherwise.
Cause/effect relationships are much more dynamic and interchangeable than an overly simplistic materialist conception can account for. To claim oneself is merely a fact, or dictated by the situation, is objective madness. To claim pure transcendence-in-itself is also incorrect. They're both forms of self-distraction used to avoid bearing responsibility for our actions. We are the transcendence of our facticity.
