Great books are great teachers; they are showing us every day what ordinary people are capable of. These books come out of ignorant, inquiring humani… - Robert Maynard Hutchins

The facts are indispensable; they are not sufficient. To solve a problem it is necessary to think. It is necessary to think even to decide what facts to collect. Even the experimental scientist cannot avoid being a liberal artist, and the best of them, as the great books show are men of imagination and of theory as well as patient observers of particular facts. ... critics have themselves frequently misunderstood the scientific method and have confused it with the aimless accumulation of facts.

Because of experimental science we know a very large number of things about the natural world of which our predecessors were ignorant. In the great books we can observe the birth of science, applaud the development of the experimental technique, and celebrate the triumphs it has won. But we can also note the limitations of the method and mourn the errors that its misapplication has caused. We can distinguish the outlines of those great persistent problems that the method ... may never solve and find the clues to their solutions offered by other methods and other disciplines.

One voice in the Great Conversation itself announces this modern point of view. In the closing paragraph of his An Enquiry Concerning Human Understanding, David Hume writes: "When we run over libraries, persuaded of these principles, what havoc must we make? If we take in our hand any volume ... let us ask, Does it contain any abstract reasoning concerning quantity or number? No. Does it contain any experimental reasoning concerning matter of fact and existence? No. Commit it then to flames: for it can contain nothing but sophistry and illusion." ... the positivists of our own day, would commit to burning or, what is the same, to dismissal from serious consideration ... Those books ... argue the case against the kind of positivism that asserts that everything except mathematics and experimental science is sophistry and illusion. ... The Great Conversation ... contains both sides of the issue.
