Gratitude is a species of justice.

Those whose abilities or knowledge incline them most to deviate from the general round of life are recalled from eccentricity by the laws of their existence.

But though it cannot be reasonable not to gain happiness for fear of losing it, yet it must be confessed, that in proportion to the pleasure of possession, will be for some time our sorrow for the loss.

Sorrow is the mere rust of the soul. Activity will cleanse and brighten it.

A man ought to read just as inclination leads him, for what he reads as a task will do him little good.

Happiness consists in the multiplicity of agreeable consciousness.

What we read with inclination makes a much stronger impression. If we read without inclination, half the mind is employed in fixing the attention; so there is but one half to be employed on what we read.
