“One thing is certain, however, and that is, that the most powerful instinct of human nature, the instinct to struggle and survive, the instinct to be superior, must be destroyed or greatly subordinated before the state here outlined can be realized; for the ideal state will be practically bereft of opportunity for its satisfaction.”

Idea for a Universal History from a Cosmopolitan Point of View (1784)
Context: Reason in a creature is a faculty of widening the rules and purposes of the use of all its powers far beyond natural instinct; it acknowledges no limits to its projects. Reason itself does not work instinctively, but requires trial, practice, and instruction in order gradually to progress from one level of insight to another. Therefore a single man would have to live excessively long in order to learn to make full use of all his natural capacities. Since Nature has set only a short period for his life, she needs a perhaps unreckonable series of generations, each of which passes its own enlightenment to its successor in order finally to bring the seeds of enlightenment to that degree of development in our race which is completely suitable to Nature’s purpose. This point of time must be, at least as an ideal, the goal of man’s efforts, for otherwise his natural capacities would have to be counted as for the most part vain and aimless. This would destroy all practical principles, and Nature, whose wisdom must serve as the fundamental principle in judging all her other offspring, would thereby make man alone a contemptible plaything.

Second Thesis
Paraphrased variant: Reason does not work instinctively, but requires trial, practice, and instruction in order to gradually progress from one level of insight to another.

Context: Goods offered as means of gaining social prestige make their appeals to one of the most profound of the human instincts. In monarchies this instinct is regarded as a mere tendency to imitate royalty. In America, with no such excuse, the eagerness with which we attempt to secure merchandise used by the "swell and swagger" is absurd, but it makes it possible for the advertiser to secure more responses than might otherwise be possible.. As an illustration of this fact we need but to look at the successful advertisements of clothing, automobiles, etc. The quality of the goods themselves does not seem to be so important as the apparent prestige given by the possession of the goods.
