This means that to entrust to science - or to deliberate control according to scientific principles - more than scientific method can achieve may have deplorable effects.

True science is never speculative it employs hypotheses as suggesting points for inquiry, but it never adopts the hypotheses as though they were demonstrated propositions.

Just as the science and art of agriculture depend upon chemistry and botany, so the art of education depends upon physiology and psychology.

The older generation had greater respect for land than science. But we live in an age when science, more than soil, has become the provider of growth and abundance. Living just on the land creates loneliness in an age of globality.

It's time to let science and medicine, not politics and rhetoric, lead us to good, sound policy.

The science of politics is the one science that is deposited by the streams of history, like the grains of gold in the sand of a river and the knowledge of the past, the record of truths revealed by experience, is eminently practical, as an instrument of action and a power that goes to making the future.

The worst state of affairs is when science begins to concern itself with art.

Politics is not an exact science.

We have failed to protect science against speculative extensions of nature, continuing to assign physical and mathematical properties to hypothetical entities beyond what is observable in nature.
