Everything is self-evident.
But in my opinion, all things in nature occur mathematically.
I accept no principles of physics which are not also accepted in mathematics.
I am accustomed to sleep and in my dreams to imagine the same things that lunatics imagine when awake.
Illusory joy is often worth more than genuine sorrow.
And I shall always hold myself more obliged to those by whose favour I enjoy uninterrupted leisure than to any who might offer me the most honourable positions in the world.
