If we value independence, if we are disturbed by the growing conformity of knowledge, of values, of attitudes, which our present system induces, then we may wish to set up conditions of learning which make for uniqueness, for self-direction, and for self-initiated learning.
A tutor should not be continually thundering instruction into the ears of his pupil, as if he were pouring it through a funnel, but, after having put the lad, like a young horse, on a trot, before him, to observe his paces, and see what he is able to perform, should, according to the extent of his capacity, induce him to taste, to distinguish, and to find out things for himself; sometimes opening the way, at other times leaving it for him to open; and by abating or increasing his own pace, accommodate his precepts to the capacity of his pupil.
Humans may crave absolute certainty; they may aspire to it; they may pretend, as partisans of certain religions do, to have attained it. But the history of science — by far the most successful claim to knowledge accessible to humans teaches that the most we can hope for is successive improvement in our understanding, learning from our mistakes, an asymptotic approach to the Universe, but with the proviso that absolute certainty will always elude us. We will always be mired in error. The most each generation can hope for is to reduce the error bars a little, and to add to the body of data to which error bars apply.
Some people claim that it is okay to read trashy novels because sometimes you can find something valuable in them. You can also find a crust of bread in a garbage can, if you search long enough, but there is a better way.
The sweetest and most inoffensive path of life leads through the avenues of science and learning; and whoever can either remove any obstruction in this way, or open up any new prospect, ought so far, to be esteemed a benefactor to mankind.
