We know more than we can tell.

Tacit knowledge is the kind of knowledge which is difficult to transfer to another person by means of writing it down or verbalizing it.

All knowledge is either tacit or rooted in tacit knowledge.

The pursuit of science is not a pursuit of knowledge, but a pursuit of truth.

Discovery is not a logical process.

The ideal of a completely detached, impersonal, and objective knowledge is a delusion.

Science is a community of truth-seekers.

Freedom in science is not a luxury, but a necessity.

The scientist's personal commitment is an indispensable part of knowing.

The act of knowing includes an appraisal of what is known.

We can know more than we can prove, and we can prove more than we can formalize.

The structure of tacit knowing is that we attend from something to something else.

The scientist's passion for discovery is the ultimate source of scientific progress.

The pursuit of science is a moral enterprise.

Objectivity is not the absence of personal commitment, but the commitment to a truth that transcends personal opinion.

The mind is not a passive recipient of information, but an active participant in the construction of knowledge.

The scientist's intuition is a vital part of the discovery process.

The scientific method is not a set of rules, but a way of life.

The freedom of science is essential for the advancement of knowledge.

The pursuit of truth is an act of faith.
