Viktor E. Frankl

The present danger does not really lie in the loss of universality on the part of the scientist, but rather in his pretence and claim of totality. . . . What we have to deplore therefore is not so much that scientists are specialising, but rather the fact that specialists are generalising.

[Quoted by E.F. Schumacher in A Guide for the Perplexed, Chapter 1, "On Philosophical Maps"]
