If you wanted something ennobling to think about, it seems you’d want to think about the human race. In fact, Robinson Jeffers believed you would do better to think about nature:
Man is a part of nature, but a nearly infinitesimal part; the human race will cease after a while and leave no trace, but the great splendors of nature will go on. Meanwhile most of our time and energy are necessarily spent on human affairs; that can’t be prevented, though I think it should be minimized; but for philosophy, which is an endless research of truth, and for contemplation, which can be a sort of worship, I would suggest that the immense beauty of the earth and the outer universe, the divine “nature of things,” is a more rewarding object. Certainly it is more ennobling. It is a source of strength; the other of distraction.
