There is a story of some mountains of salt in Cumana, which never diminished, though carried away in much abundance by merchants; but when once they were monopolized to the benefit of a private purse, then the salt decreased; till afterward all were allowed to take of it, when it had a new access and increase. The truth of this story may be uncertain, but the application is true; he that envies others the use of his gifts decays then, but he thrives most that is most diffusive.
Herbert SpencerIf there be an order in which the human race has mastered its various kinds of knowledge, there will arise in every child an aptitude to acquire these kinds of knowledge in the same order. So that even were the order intrinsically indifferent, it would facilitate education to lead the individual mind through the steps traversed by the general mind. But the order is not intrinsically indifferent; and hence the fundamental reason why education should be a repetition of civilization in little.
Herbert Spencer
