Paul Valéry said this quote

Une philosophie doit etre portative.

~ Paul Valéry

God created man and, finding him not sufficiently alone, gave him a companion to make him feel his solitude more keenly

~ Paul Valéry

God made everything out of nothing. But the nothingness shows through.

~ Paul Valéry

Nothing is more natural than mutual misunderstanding; the contrary is always surprising. I believe that one never agrees on anything except by mistake, and that all harmony among human beings is the happy fruit of an error.

~ Paul Valéry
