Valéry alludes to a famous pensée of Blaise Pascal: 'The eternal silence of these infinite spaces affrights me.' (Pensées, no. 201).
More quotes by Paul Valéry
My soul is nothing now but the dream dreamt by matter struggling with itself!
That which has always been accepted by everyone, everywhere, is almost certain to be false.
To construct oneself, to know oneself—are these two distinct acts or not?

To sin by silence, when we should protest,
Makes cowards out of men.
Blessed is the man who, having nothing to say, abstains from giving us wordy evidence of the fact.
There are times when good words are to be left unsaid out of esteem for silence.
