The argument from consciousness is an argument for the existence of God based on consciousness. The best-known defender of the argument from consciousness is J. P. Moreland.
The argument may be stated in inductive or deductive form An alternate, closely related, version of the argument uses Platonism as its premise in a deductive argument. 
Richard Swinburne put forward an inductive form of the argument in his book The Existence of God. He uses the argument from personal identity for mind-body dualism to show that we have a non-physical mental element to our minds. He suggests that the most probable way in which the non-physical and the physical are linked in causal-interaction is by design- which implies a designer. Swinburne suggests that this designer is God. He says that whilst this argument, owing to its inductive form, is inconclusive, it does provide strong evidence for a God.
Theists such as Robert Adams have advanced a slightly different version of Swinburne's argument which focuses on mental/physical correlations and not merely the existence of mental states. These are similar to Swinburne's argument but take a deductive form rather than an inductive one.
William Lane Craig put the argument from consciousness as follows:
Peter Kreeft has put forward a deductive form of the argument from consciousness based upon the intelligibility of the universe despite the limitations of our minds. He phrases it deductively as follows:
He compares his argument to C. S. Lewis' argument from reason.
The Christian philosopher Augustine of Hippo formed a formulation of the argument from consciousness, sometimes termed the Argument from truth which is closely aligned to consciousness, whilst using neither inductive nor deductive methodology. The argument was influenced by Platonism.
The Catholic philosopher Peter Kreeft, whilst he feels that it could be an effective argument, feels that we have too little knowledge of the workings of consciousness for this to be truly convincing as of yet. 
Another Catholic philosopher, Edward Feser has promoted the Augustinian argument, including it in his book Five Proofs of the Existence of God.  He concludes that Augustine's argument is valid, having given many different reasons why Platonism, its primary premise, is true.
His inclusion of the argument led to an extremely critical review of his book on the existence of God to be published  by Richard Carrier. His criticism is that Feser misunderstands the argument and confuses potentiality and actuality. Feser responded to Carrier's criticisms, saying, "Pop atheist writer Richard Carrier grandly claims to have “debunked!” (exclamation point in the original) Five Proofs of the Existence of God. It’s a bizarrely incompetent performance. To say that Carrier attacks straw men would be an insult to straw men, which usually bear at least a crude resemblance to the argument under consideration." He deals with Carrier's objections, concluding the article by writing "It is hard to believe that Carrier actually read Five Proofs through, but I certainly did not bother to read the rest of his critique, judging that if what he has to say about the Aristotelian proof is this awful, it would be a waste of time and energy to proceed any further. If any reader has bothered to read it and found some gold among the dross, feel free to call our attention to it in the combox below."
Carrier himself responded  to Feser's critique of his critique, by writing, "I had a good laugh when Feser fans claimed he “destroyed” my critique this week, and at first thought, “Oh gosh, did I get something wrong I need to correct?” And then I read his reply. Face, meet palm. Holy cow. His response is wildly inept. I’ll lay it out for you here." Feser replied by writing, "Carrier’s self-confidence is so absurdly out of proportion to his actual competence that he does not realize that the only deathblows he delivers are of the self-inflicted kind. In particular, in no fewer than three places in his response, Carrier has inadvertently revealed himself to be either an extremely reckless liar or guilty of malpractice that would make any actual scholar (as opposed to the online hobbyist Carrier is) a professional laughingstock." He pointed out in his article three places in which Carrier contradicts himself, and states that to reply any further to Carrier would be to give him more credit than he deserves. 
The first premise, assertion that non-physical mental states exist, implies a dualist view of mind. Therefore, one line of attack is to argue the case for physicalism about the human mind. Moreland takes the arguments for the first premise and refers to classic defenses of dualism. However, the first premise is rejected by many philosophers of mind. Frank Jackson, known for the knowledge argument in support of dualism about the mind, comments on the debate between physicalist and dualist conceptions of mind:
Much of the contemporary debate in the philosophy of mind is concerned with the clash between certain strongly held intuitions and what science tells us about the mind and its relation to the world. What science tells us about the mind points strongly towards some version or other of physicalism. The intuitions, in one way or another, suggest that there is something seriously incomplete about any purely physical story about the mind ... Most contemporary philosophers given a choice between going with science and going with intuitions, go with science. Although I once dissented from the majority, I have capitulated and now see the interesting issue as being where the arguments from the intuitions against physicalism—the arguments that seem so compelling—go wrong.
If one is willing to accept the first premise that reductive forms of physicalism are false, then the argument takes off. Thus, one could think of Moreland as making an argument that tries to move a person from "rejecting physicalism" to "accepting theism". The crucial step in this move is the fifth premise, which asserts that naturalism can not account for non-physical mental states. A critique of this premise is offered by Andrew Melnyk:
Naturalism can easily explain how the universe came to contain physically irreducible conscious occurrences. It can do so by supposing that, among the fundamental laws governing the universe, there are some according to which, whenever such-and-such complex nonconscious occurrences occur, so-and-so conscious occurrences occur; perhaps such a law says that, whenever a human brain attains a certain kind and degree of complexity, a pain is experienced. Given such laws, the capacity for consciousness that some creatures enjoy, like the capacity for breathing, can be explained as having arisen through natural selection. Through mutation, some creature was born with a brain of the requisite kind and degree of complexity to generate conscious experiences; and then, because these experiences increased the creature's fitness, such creatures were selected for.
However Moreland charges that such attempts to accommodate consciousness within an atheistic worldview are ad hoc and contrived and fail to take into account many features of conscious experience. Moreland spends much of the book defending this premise against philosophers, such as Michael Martin, who accept pluralist naturalism. He also critiques contemporary philosophers of mind such as John Searle, Timothy O' Connor, Colin McGinn, David Skriba, Philip Clayton and Jaegwon Kim, who attempt to account for consciousness.
Finally, one can also question premise eight: why does a personal explanation have to lead to monotheistic (as opposed to deistic or polytheistic) accounts of intention? However, Moreland maintains that questioning these minor premises is of little consolation to the naturalist as they essentially constitute intramural theist debates, and that for most westerners theism is the only viable candidate to accommodate personal explanations. Similarly Occam's razor can be applied so only one personal agent is required.
