The basic idea of Western science is that you don't have to take into account the falling of a leaf on some planet in another galaxy when you're trying to account for the motion of a billiard ball on a pool table on earth. Very small influences can be neglected. There's a convergence in the way things work, and arbitrarily small influences don't blow up to have arbitrarily large effects.

Every new medium transforms the nature of human thought. In the long run, history is the story of information becoming aware of itself.

I can't remember the last book that taught me so much, and so well, about what it means to be human.

Writing comes into being to retain information across time and across space. Before writing, communication is evanescent and local; sounds carry a few yards and fade to oblivion. The evanescence of the spoken word went without saying. So fleeting was speech that the rare phenomenon of the echo, a sound heard once and then again, seemed a sort of magic.

At its most fundamental, information is a binary choice. In other words, a single bit of information is one yes-or-no choice.

It is not true that people who accomplish things don't waste time and that people who waste time don't accomplish things. The very concept is ill-informed. You can't waste time and you can't save time; you can only choose what you do at any given moment.

When information is cheap, attention becomes expensive.
