Is There a Causal Loop Which Avoids a First Cause?

I examine whether there exists a causal loop which avoids a First Cause. I distinguish between a causal loop in dynamic and static time and between an open and closed loop, and explain that a dynamic loop and an open loop does not avoid a First Cause. I note that a static closed loop cosmological model has been proposed by Gott and Li (Physical Review D 58:023501–1, 1998), and that we do not have adequate evidence for thinking that such a loop exists. I discuss the Bootstrap Paradox which shows that this type of causal loop is viciously circular and metaphysically impossible.
