Context: I agree … that a professorship of Theology should have no place in our institution. But we cannot always do what is absolutely best. Those with whom we act, entertaining different views, have the power and the right of carrying them into practice. Truth advances, and error recedes step by step only; and to do to our fellow men the most good in our power, we must lead where we can, follow where we cannot, and still go with them, watching always the favorable moment for helping them to another step.

Context: Religious people often say that religion offers absolute certainty about right and wrong; "god tells them" what it is. Even supposing that the aforementioned gods exist, and that the believers really know what the gods think, that still does not provide certainty, because any being no matter how powerful can still be wrong. Whether gods exist or not, there is no way to get absolute certainty about ethics. Without absolute certainty, what do we do? We do the best we can. Injustice is happening now; suffering is happening now. We have choices to make now. To insist on absolute certainty before starting to apply ethics to life decisions is a way of choosing to be amoral.
