“People should recognize the importance of reasonable pricing rather than looking for bargain basement trips, because safety must be the paramount concern.”

The Value of Science (1955)
Context: The scientist has a lot of experience with ignorance and doubt and uncertainty, and this experience is of very great importance, I think. When a scientist doesn’t know the answer to a problem, he is ignorant. When he has a hunch as to what the result is, he is uncertain. And when he is pretty darn sure of what the result is going to be, he is still in some doubt. We have found it of paramount importance that in order to progress we must recognize our ignorance and leave room for doubt. Scientific knowledge is a body of statements of varying degrees of certainty — some most unsure, some nearly sure, but none absolutely certain. Now, we scientists are used to this, and we take it for granted that it is perfectly consistent to be unsure, that it is possible to live and not know. But I don’t know whether everyone realizes this is true. Our freedom to doubt was born out of a struggle against authority in the early days of science. It was a very deep and strong struggle: permit us to question — to doubt — to not be sure. I think that it is important that we do not forget this struggle and thus perhaps lose what we have gained.

1770s, African Slavery in America (March 1775)
Context: TO AMERICANS. THAT some desperate wretches should be willing to steal and enslave men by violence and murder for gain, is rather lamentable than strange. But that many civilized, nay, christianized people should approve, and be concerned in the savage practice, is surprising; and still persist, though it has been so often proved contrary to the light of nature, to every principle of Justice and Humanity, and even good policy, by a succession of eminent men, and several late publications.
