Whence come I and whither go I? That is the great unfathomable question. Science has no answer to it.

What we observe as material bodies and forces are nothing but shapes and variations in the structure of space.

From all we have learnt about the structure of living matter, we must be prepared to find it working in a manner that cannot be reduced to the ordinary laws of physics. And that not on the ground that there is any 'new force' or what not, directing the behaviour of the single atoms within a living organism, but because the construction is different from anything we have yet tested in the physical laboratory.

The mathematical framework of quantum theory has passed countless successful tests and is now universally accepted as a consistent and accurate description of all atomic phenomena.

[Plato] was the first to envisage the idea of timeless existence and to emphasize it-against reason-as a reality, more [real] than our actual experience.

The task is not to see what has never been seen before, but to think what has never been thought before about what you see everyday.

In Darwin's theory, you just have to substitute 'mutations' for his 'slight accidental variations' (just as quantum theory substitutes 'quantum jump' for 'continuous transfer of energy'). In all other respects little change was necessary in Darwin's theory...
