“Should I be surprised that dangers which have always surrounded me should at last attack me? A great part of mankind, when about to sail, do not think of a storm. I shall never be ashamed of a reporter of bad news in a good cause.”
Variant translation: I shall never be ashamed of citing a bad author if the line is good.

Dialogues Concerning Natural Religion (1779)
Context: In such a chain, too, or succession of objects, each part is caused by that which preceded it, and causes that which succeeds it. Where then is the difficulty? But the WHOLE, you say, wants a cause. I answer, that the uniting of these parts into a whole, like the uniting of several distinct countries into one kingdom, or several distinct members into one body, is performed merely by an arbitrary act of the mind, and has no influence on the nature of things. Did I show you the particular causes of each individual in a collection of twenty particles of matter, I should think it very unreasonable, should you afterwards ask me, what was the cause of the whole twenty. This is sufficiently explained in explaining the cause of the parts.
