Every body continues in its state of rest or uniform motion in a straight line, except insofar as it doesn't.

Events do not happen; they are just there, and we come across them.

The idea of a universal mind or Logos would be, I think, a fairly plausible inference from the present state of scientific theory.

I believe there are 15, 747, 724, 136, 275, 002, 577, 605, 653, 961, 181, 555, 468, 044, 717, 914, 527, 116, 709, 366, 231, 425, 076, 185, 631, 031, 296 protons in the universe and the same number of electrons.

[When thinking about the new relativity and quantum theories] I have felt a homesickness for the paths of physical science where there are ore or less discernible handrails to keep us from the worst morasses of foolishness.

Philosophically, the notion of a beginning of the present order of Nature is repugnant to me ... I should like to find a genuine loophole.

We have found that where science has progressed the farthest, the mind has but regained from nature that which the mind put into nature.
