Arthur Schopenhauer on Mind

"The brain may be regarded as a kind of parasite of the organism, a pensioner, as it were, who dwells with the body."

"Noise is the most impertinent of all forms of interruption. It is not only an interruption, but also a disruption of thought."

"A man who has no mental needs, because his intellect is of the narrow and normal amount, is, in the strict sense of the word, what is called a philistine."

"A man’s body and the needs of his body are now everywhere treated with a tender indulgence. Is the thinking mind then, to be the only thing that is never to obtain the slightest measure of consideration or protection, to say nothing of respect?"

"Truth that has been merely learned is like an artificial limb, a false tooth, a waxen nose; at best, like a nose made out of another's flesh; it adheres to us only because it is put on. But truth acquired by thinking of our own is like a natural limb; it alone really belongs to us. This is the fundamental difference between the thinker and the mere man of learning. The intellectual attainments of a man who thinks for himself resemble a fine painting, where the light and shade are correct, the tone sustained, the colour perfectly harmonised; it is true to life. On the other hand, the intellectual attainments of the mere man of learning are like a large palette, full of all sorts of colours, which at most are systematically arranged, but devoid of harmony, connection and meaning."

"Truth that is naked is the most beautiful, and the simpler its expression the deeper is the impression it makes; this is partly because it gets unobstructed hold of the hearer’s mind without his being distracted by secondary thoughts, and partly because he feels that here he is not being corrupted or deceived by the arts of rhetoric, but that the whole effect is got from the thing itself."

"In youth it is the outward aspect of things that most engages us; while in age, thought or reflection is the predominating quality of the mind. Hence, youth is the time for poetry, and age is more inclined to philosophy. In practical affairs it is the same: a man shapes his resolutions in youth more by the impression that the outward world makes upon him; whereas, when he is old, it is thought that determines his actions."

"A man of intellect is like an artist who gives a concert without any help from anyone else, playing on a single instrument — a piano, say, which is a little orchestra in itself. Such a man is a little world in himself; and the effect produced by various instruments together, he produces single-handed, in the unity of his own consciousness. Like the piano, he has no place in a symphony; he is a soloist and performs by himself — in solitude, it may be; or if in the company with other instruments, only as principal; or for setting the tone, as in singing."

"The poet presents the imagination with images from life and human characters and situations, sets them all in motion and leaves it to the beholder to let these images take his thoughts as far as his mental powers will permit. This is why he is able to engage men of the most differing capabilities, indeed fools and sages together. The philosopher, on the other hand, presents not life itself but the finished thoughts which he has abstracted from it and then demands that the reader should think precisely as, and precisely as far as, he himself thinks. That is why his public is so small."

"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."
