Dissent is the mark of freedom. - Jacob Bronowski

What we really mean by free will... is the visualizing of alternatives and making a choice between them. ...the central problem of human consciousness depends on this ability to imagine.

There is today almost no scientific theory which was held when, say, the Industrial Revolution began about 1760. Most often today's theories flatly contradict those of 1760; many contradict those of 1900. In cosmology, in quantum mechanics, in genetics, in the social sciences, who now holds the beliefs that seemed firm sixty years ago? Yet the society of scientists has survived these changes without a revolution, and honors the men whose beliefs it no longer shares. No one has recanted abjectly at a trial before his colleagues. The whole structure of science has been changed and no one has been either disgraced or deposed. Through all the changes of science, the society of scientists is flexible and single-minded together, and evolves and rights itself. In the language of science, it is a stable society.

The world today is made, it is powered by science; and for any man to abdicate an interest in science is to walk with open eyes towards slavery.
