And that is exactly why I postulated that our impulse risk our lives to help people is actually stronger than our impulse for self-interest, though we do not feel the impulse.
When most people describe placing themselves in danger, they usually describe three impulses:
- Self-preservation, which they experience as being the stronger impulse.
- Desire to help someone in need, which they experience to be the weaker impulse.
- A third impulse, the conscience, which says that one ought to go with #2, even though it is the weakest of them.
People cannot be experiencing Impulse #2 as the weaker impulse and at the same time this impulse is somehow stronger and not felt. Consider this in light of the following from
Mere Christianity:
We all know what it feels like to be prompted by instinct – by mother love, or sexual instinct, or the instinct for food. It means that you feel a strong want or desire to act in a certain way. And, of course, we sometimes do feel just that sort of desire to help another person: and no doubt that desire is due to the herd instinct. But feeling a desire to help is quite different from feeling that you ought to help whether you want to or not.
- C.S. Lewis, Mere Christianity (New York: Touchstone, 1996), 22.
In terms of Impulse #3 in my above outline, C.S. Lewis states…
Now this thing that judges between the two instincts, that decides which should be encouraged, cannot itself be either of them. You might as well say that the sheet of music which tells you, at a given moment, to play one note on the piano and not another, is itself one of the notes on the keyboard. The Moral Law tells us the tune we have to play: our instincts are merely the keys.
-Ibid, 23.
The point I’m trying to make is that Peter Kreeft must make a case against such a conclusion if he is going to accomplish his intent, which is to prove the existence of God. Though this video does seem to show that moral objectivity is incompatible with naturalism, it does not show that God exists. Of course, not making a case against this conclusion is just one of the reasons why the argument made in this video is unsound. let’s look at the five-point outline I provided in more detail.
Kreeft is showing that if our physical reality is not responsible for the Moral Law then we need to look for a Lawgiver who transcends or physical reality. I admit that his video is far-reaching in what it promises, but it presents a method in critical thinking that does allow people to continue this philosophical examination on their own and reach the same conclusions he makes. Just because his video is far-reaching does not make it unsound.
Or perhaps it all depends on what is meant by “unsound”. To me, “unsound” means that Kreeft utilized fallacious reasoning, and/or the video has no real merit (which is what my long debate with inocente examined). But if by “unsound” you mean that Kreeft’s video does not, in and of itself, make a clear philosophical case for the Judeo-Christian concept of God then I would have to agree. But I think the video has merit all the same.
I suppose you’re right. I was only thinking of all the vocal atheists that I have personally encountered. I have never met met or heard from an atheist yet who supported the idea of an objective morality. Just look at the atheists on this thread who’ve commented on the subject. Both Regular Atheist and Trurl support subjective moralities. I can’t tell what Eleve believes, but she seems to be supporting universal morality rather than objective morality. (great distinction, BTW.

) but in any case, regardless of whether or not most atheists support objective morality, it is certainly true that not all atheists appeal to it, which means Kreeft’s very first premise is unsound.
Maybe not all atheists actually appeal to it, but I would say many and probably most do in their daily lives, whether they realize it or not. Trurl
claimed that he believed in subjective-only morality, and to an extent so did inocente (although inocente is not an atheist; also, inocente seemed to support the idea that the Golden Rule was the only type of authentic objective morality), but neither could give me straight answers when I put tried to put these beliefs to the test. RA stated that he did not make appeals to objective morality, but people who read this thread can ask themselves how accurately his theory that morality is “personal opinion & nothing more” reflects their own human experience in matters of morality.
I’m guessing that Kreeft’s target audience (or at least the one he hopes for) are the atheists who resemble C.S. Lewis prior to his conversion. The beliefs of atheists are varied and there is no such thing as a video that can address all of them. I think therefore that there is merit in Kreeft designing a short video to address the many people who make appeals to objective morality (whether they realize it or not, or whether they want to admit it or not).
As a side note, in terms of the distinction between a universal morality and objective morality, the manner by which universal morality has been defined in this thread shows that it is still a subjective-only system of morality. Therefore, it cannot be realistically used to make appeals to objective morality.
