I would teach the world that science is the best way to understand the world and that for any set of observations, there is only one correct explanation. Also, science is value-free, as it explains the world as it is. Ethical issues arise only when science is applied to technology - from medicine to industry.

Reliable scientific knowledge is value free and has no moral or ethical value. Science tells us how the world is. ... Dangers and ethical issue arise only when science is applied as technology.

The image of the disinterested, dispassionate scientist is no less false than that of the mad scientist who is willing to destroy the world for knowledge.

I regard it as ethically unacceptable and impractical to censor any aspect of trying to understand the nature of our world.

When it was suggested to Pasteur that many of his great achievements depended on luck, he replied - I'm sure with more than a little irritation - 'In the field of observation in science, fortune only favours the prepared mind.' It is not by chance that it is always the great scientists who have the luck.
