I have never found a companion that was so companionable as solitude. We are for the most part more lonely when we go abroad among men than when we stay in our chambers. A man thinking or working is always alone, let him be where he will.

They can do without architecture who have no olives nor wines in the cellar.

This world is but a canvas to our imagination.

The perception of beauty is a moral test.
