Far from being magisterial in its objectivity, science was conditioned by history, society, and the prejudices of scientists.

Rather than being an interpreter, the scientist who embraces a new paradigm is like the man wearing inverting lenses.

Under normal conditions the research scientist is not an innovator but a solver of puzzles, and the puzzles upon which he concentrates are just those which he believes can be both stated and solved within the existing scientific tradition.

Normal science does not aim at novelties of fact or theory and, when successful, finds none.

The crises of our time, it becomes increasingly clear, are the necessary impetus for the revolution now under way. And once we understand nature's transformative powers, we see that it is our powerful ally, not a force to feared our subdued.
