All intellectual improvement arises from leisure.

As to the Christian religion, besides the strong evidence which we have for it, there is a balance in its favor from the number of great men who have been convinced of its truth after a serious consideration of the question. Grotius was an acute man, a lawyer, a man accustomed to examine evidence, and he was convinced. Grotius was not a recluse, but a man of the world, who certainly had no bias on the side of religion. Sir Isaac Newton set out an infidel, and came to be a very firm believer.

When emulation leads us to strive for self-elevation by merit alone, and not by belittling another, then it is one of the grandest possible incentives to action.

All theory is against free will; all experience is for it.

Where no man thinks himself under any obligation to submit to another, and, instead of co-operating in one great scheme, every one hastens through by-paths to private profit, no great change can suddenly be made; nor is superior knowledge of much effect, where every man resolves to use his own eyes and his own judgment, and every one applauds his own dexterity and diligence, in proportion as he becomes rich sooner than his neighbour.

Criticism, as it was first instituted by Aristotle, was meant as a standard of judging well.

I have often thought that there has rarely passed a life of which a judicious and faithful narrative would not be useful; for not only every man has, in the mighty mass of the world, great numbers in the same condition with himself, to whom his mistakes and miscarriages, escapes and expedients, would be of immediate and apparent use; but there is such a uniformity in the state of man, considered apart from adventitious and separable decorations and disguises, that there is scarce any possibility of good or ill but is common to human kind.
