Apologies are seldom of any use.

Friendship may well deserve the sacrifice of pleasure, though not of conscience.

To have the management of the mind is a great art, and it may be attained in a considerable degree by experience and habitual exercise... Let him take a course of chemistry, or a course of rope-dance, or a course of any thing to which he is inclined at the time. Let him contrive to have as many retreats for his mind as he can, as many things to which it can fly from itself.

Curiosity is, in great and generous minds, the first passion and the last; and perhaps always predominates in proportion to the strength of the contemplative faculties. He who easily comprehends all that is before him, and soon exhausts any single subject, is always eager for new inquiries; and in proportion as the intellectual eye takes in a wider prospect, it must be gratified with variety, by more rapid flights and bolder excursions.

Poetry is the art of uniting pleasure with truth.

There is no kind of idleness by which we are so easily seduced as that which dignifies itself by the appearance of business.

A short letter to a distant friend is, in my opinion, an insult like that of a slight bow or cursory salutation - a proof of unwillingness to do much, even where there is a necessity of doing something.
