“From the fundamental nature of the Philistine, it follows that, in regard to others, as he has no intellectual but only physical needs, he will seek those who are capable of satisfying the latter not the former. And so of all the demands he makes of others the very smallest will be that of any outstanding intellectual abilities. On the contrary, when he comes across these they will excite his antipathy and even hatred. For here he has a hateful feeling of inferiority and also a dull secret envy which he most carefully attempts to conceal even from himself; but in this way it grows sometimes into a feeling of secret rage and rancour. Therefore it will never occur to him to assess his own esteem and respect in accordance with such qualities, but they will remain exclusively reserved for rank and wealth, power and influence, as being in his eyes the only real advantages to excel in which is also his desire.”

Der Philister … ist demnach ein Mensch ohne geistige Bedürfnisse. Hieraus nun folgt gar mancherlei: erstlich, in Hinsicht auf ihn selbst, daß er ohne geistige Genüsse bleibt; nach dem schon erwähnten Grundsatz: il n’est pas de vrais plaisirs qu’avec de vrais besoins.

Man in the Modern Age (1933)
Context: When the titanic apparatus of the mass-order has been consolidated, the individual has to serve it, and must from time to time combine with his fellows in order to renovate it. If he wants to make his livelihood by intellectual activity, he will find it very difficult to do this except by satisfying the needs of the many. He must give currency to something that will please the crowd. They seek satisfaction in the pleasures of the table, eroticism, self-assertion; they find no joy in life if one of these gratifications be curtailed. They also desire some means of self-knowledge. They desire to be led in such as way that they can fancy themselves leaders. Without wishing to be free, they would fain be accounted free. One who would please their taste must produce what is really average and commonplace, though not frankly styled such; must glorify or at least justify something as universally human. Whatever is beyond their understanding is uncongenial to them.
One who would influence the masses must have recourse to the art of advertisement. The clamour of puffery is to-day requisite even for an intellectual movement. The days of quiet and unpretentious activity seem over and done with. You must keep yourself in the public eye, give lectures, make speeches, arouse a sensation. Yet the mass-apparatus lacks true greatness of representation, lacks solemnity. <!-- pp. 43 - 44

Source: The Prince (1513), Ch. 19: 'That one should avoid being despised and hated'
Context: The prince must consider, as has been in part said before, how to avoid those things which will make him hated or contemptible; and as often as he shall have succeeded he will have fulfilled his part, and he need not fear any danger in other reproaches. It makes him hated above all things, as I have said, to be rapacious, and to be a violator of the property and women of his subjects, from both of which he must abstain. And when neither their property nor honour is touched, the majority of men live content, and he has only to contend with the ambition of a few, whom he can curb with ease in many ways. It makes him contemptible to be considered fickle, frivolous, effeminate, mean-spirited, irresolute, from all of which a prince should guard himself as from a rock; and he should endeavour to show in his actions greatness, courage, gravity, and fortitude; and in his private dealings with his subjects let him show that his judgments are irrevocable, and maintain himself in such reputation that no one can hope either to deceive him or to get round him. That prince is highly esteemed who conveys this impression of himself, and he who is highly esteemed is not easily conspired against; for, provided it is well known that he is an excellent man and revered by his people, he can only be attacked with difficulty.
