on directions Science will take.

At the present time the accumulation of facts is occuring in such a rapid flow that the simplest thing to do is just keep observing them with out trying to do much inductive research.

The position is confused and could easily push the scientific world towards a general revolution. Under these circumstances it is as well to be prepared for what might happen, but there is no point in coming out with a revolutionary theory in the dark, as it were.

The number of people who are being skeptical about whether all problems can be solved by science is now quite large. None of my scientific colleagues has the same optimism as they had 10 years ago. I think that this is an inevitable occurrence at a given level of sophistication.
