I am worn out by the insults and vexations that this work brings down on us.

Push on and faith will catch up with you.

A philosopher is a fool who torments himself while he is alive, to be talked of after he is dead.

In England it was enough that Newton was the greatest mathematican of his century; in France he would have been expected to be agreeable too.

The more wit we have, the less satisfied we are with it.

To someone who could grasp the Universe from a unified standpoint the entire creation would appear as a unique truth and necessity.

Just go on..and faith will soon return.
