Admittedly, scientific authority is not distributed evenly throughout the body of scientists; some distinguished members of the profession predominate over others of a more junior standing.

The first thing to make clear is that scientists, freely making their own choice of problems and pursuing them in the light of their own personal judgment, are in fact co-operating as members of a closely knit organization.

Of course language manifests a belief only if we use its words with the implied acceptance of their appositeness.

Admittedly, the body of scientists, as a whole, does uphold the authority of science over the lay public. It controls thereby also the process by which young men are trained to become members of the scientific profession.

But the system of prices ruling the market not only transmits information in the light of which economic agents can mutually adjust their actions, it also provides them with an incentive to exercise economy in terms of money.

I shall reconsider human knowledge by starting from the fact that we can know more than we can tell.

We could not, for example, arrive at a principle like that of entropy without introducing some additional principle, such as randomness, to this topography.
