"There is no more eloquent, interesting or persuasive exposition of what may be called science of philosophy than Sir James Jeans's." -- The New York Times
Can we have any knowledge of the world outside us other than we gain by the methods of science? Are we humans endowed with free will, or are we mere cogs in a vast machine that must follow its predestined course until it finally runs down? Is the world we perceive the world of ultimate reality, or is it only a curtain veiling a deeper reality beyond?
In this strikingly lucid and often poetic book, one of the twentieth century's greatest scientists grapples with these age-old questions, achieving in the process a brilliant and non-technical exposition of the interrelationship between physics and philosophy. He begins by defining physics and philosophy, pointing out the difference in their respective attempts to explain physical reality and man's place in it. This discussion paves the way for an outline of epistemological methods in which the rationalism of thinkers like Descartes, Leibniz, and Kant is compared to the empiricism of Locke and Hume.
Over the course of the book, in a manner that is careful and methodic but never dull, Jeans marshals the evidence for his startling conclusion: recent discoveries in astronomy, mathematics, sub-atomic physics, and other disciplines have washed away the scientific basis of many older philosophic discussions. Such long-standing problems as causality, free will and determinism, the nature of space and time, materialism and mentalism must be considered anew in the light of new knowledge and information attained by twentieth-century physical science. Even then, however, Jeans cautions against drawing any positive conclusions, pointing out that both physics and philosophy are both relatively young and that we are still in Newton's words, like children playing with pebbles on the sea-shore, while the great ocean of truth rolls, unexplored, beyond our reach.
Although first published in 1943, nothing in physics has happened to affect Jeans's account in this book; it remains remarkably fresh and undated, a classic exposition of the philosophical implications of scientific knowledge.

Author Notes

Sir James Jeans: Science Made Simple
Sir James Jeans (1877--1946), English physicist, astronomer, and mathematician, made substantial contributions to many areas of science including quantum theory, the theory of radiation, and stellar evolution, but is most remembered today for several elegantly written books on science and its meaning for the general reader. Among these are the classics Physics and Philosophy , published by Dover in 1981, and Science and Music, published by Dover in 1968.

In the Author's Own Words:
"Put three grains of sand inside a vast cathedral, and the cathedral will be more closely packed with sand than space is with stars."

"Life exists in the universe only because the carbon atom possesses certain exceptional properties."

"The human race, whose intelligence dates back only a single tick of the astronomical clock, could hardly hope to understand so soon what it all means."

From Physics and Philosophy :
"Science usually advances by a succession of small steps, through a fog in which even the most keen-sighted explorer can seldom see more than a few paces ahead. Occasionally the fog lifts, an eminence is gained, and a wider stretch of territory can be surveyed -- sometimes with startling results. A whole science may then seem to undergo a kaleidoscopic rearrangement, fragments of knowledge sometimes being found to fit together in a hitherto unsuspected manner. Sometimes the shock of readjustment may spread to other sciences; sometimes it may divert the whole current of human thought."
