Knowledge

Love takes up where knowledge leaves off

Only divine love bestows the keys of knowledge

Art is the most intense mode of individualism that the world has known

By the work one knows the workman

The business of art is to reveal the relation between man and his environment.

Art is a step from what is obvious and well-known toward what is arcane and concealed

Everything I know I learned after I was thirty

Travelling expands the mind rarely

Good nature is worth more than knowledge, more than money, more than honor, to the persons who possess it.

Knowledge comes, but wisdom lingers

Like all great travelers, I have seen more than I remember, and remember more than I have seen

We never know the love of a parent till we become parents ourselves

The world is a country which nobody ever yet knew by description; one must travel through it one's self to be acquainted with it.

Men often act knowingly against their interest

Everything has been figured out, except how to live

To affect the quality of the day, that is the highest of arts.

Life is half spent before we know what it is

They know enough who know how to learn

I live in the world rather as a spectator of mankind than as one of the species

The utmost extent of man's knowledge, is to know that he knows nothing
