PERSONAL KNOWLEDGE

rather the scientist s personal participation in his knowledge, both in its discovery and its validation, is an indispensable part of science itself. Even in the exact sciences knowing is an art, in which the skill of the knower, guided by his passionate sense of increasing contact with reality, forms a logically necessary part. In the biological and social sciences this becomes even more evident. Polanyi argues against the urge to make knowledge impersonal.
