Since abstract objects are causally impotent by definition, they cannot be the cause of the universe, and thus are unlikely to be that which has always existed. That leaves us with an unembodied mind as the eternal reality. This makes sense. But just because we are not personally acquainted with the idea of an unembodied mind does not mean an unembodied mind does not, or cannot exist. Neither does it constitute good grounds on which to reject the evidence being presented for the existence of such a mind. The scientific argument provides warrant for believing in something we may not have thought probable otherwise. Second, even if we are not personally familiar with unembodied minds, we are very familiar with the concept of mind(each of us has one), and its causal powers. In other words, even if the specific form of the mind in question is unfamiliar to us, the function of a mind very familiar to us: minds exercise causal agency. And I see no reason to think the capacity is dependent on our mind being embodied. The property of causal agency belongs to the mind, not the body, so there is no reason to think an unembodied mind is too abstract a concept to be the cause of our universe. One might respond that it would be impossible for an unembodied mind (immaterial) to cause effects in the physical realm. This must be false. Why? Because our minds cause effects in the physical realm all the time, and our minds are an immaterial entity (it may stand in a causal relationship with the brain, but it cannot be reduced to the brain(physically). The only difference between our minds and an unembodied mind is embodiment, but I fail to see how embodiment is significant. The fact remains that human minds, as well as a Divine mind, are immaterial in nature, and a source of causation which produces effects in the physical world. A case could even be made that human minds do not have to be embodied, and indeed, become disembodied 8upon death. I am thinking in particular of empirical studies into near-death experiences. While many of the experiences are unverifiable, a small minority are. And in these instances, there are examples of continued consciousness, even after brain death. In fact, in some cases the person is conscious of things happening outside of the room where their body lies(things they could not have possibly known, even if their body were functioning normally). So I don't think the idea of an unembodied mind is abstract, or that we are not acquainted with this. Even if most of us are unacquainted with it experimentally, we are acquainted with the concept, and there is nothing incoherent about the concept. Strange, maybe, but incoherent, no.
