Too many facts are often as much of an obstacle to understanding as too few. There is a sense in which we moderns are inundated with facts to the det… - Mortimer J. Adler

A report of the Carnegie Foundation recommended the abolition of the undergraduate bachelor of science degree in education leading to the state certification of teachers. Schools of education should become research institutions at the graduate level of the university and not places for the training of schoolteachers. Those planning to enter the profession of teaching should have four years of general, liberal education at the college level, and then three years of practice teaching under supervision... the best teacher is one who learns in the process of teaching.

To avoid this error, the error of assuming that that to be widely read and to be well read are the same thing, we must consider a certain distinction in types of learning. ... In the history of education, men have often distinguished between learning by instruction and learning by discovery. ... Discovery stands to instruction as learning without a teacher stands to learning through the help of one. In both cases the activity of learning goes on in the one who learns. It would be a mistake to suppose that discovery is active learning, and instruction passive. There is no inactive learning, just as there is no inactive reading. This is so true, in fact, that a better way to make the distinction clear is to call instruction “aided discovery.”

[Television, radio, and magazines] are so designed as to make thinking seem unnecessary (though this is only an appearance). The packaging of intellectual positions and views is one of the most active enterprises of some of the best minds of our day. The viewer of television, the listener to radio, the reader of magazines, is presented with a whole complex of elements—all the way from ingenious rhetoric to carefully selected data and statistics—to make it easy for him to “make up his own mind” with the minimum of difficulty and effort. But the packaging is often done so effectively that the viewer, listener, or reader does not make up his own mind at all. Instead, he inserts a packaged opinion into his mind, somewhat like inserting a cassette into a cassette player. He then pushes a button and “plays back” the opinion whenever it seems appropriate to do so. He has performed acceptably without having had to think.
