I read these words which are the sum of all moral philosophy, and which cut short all the disputes of the casuists: When in doubt if an action is good or bad, refrain.
The fact that man produces a concept "I" besides the totality of his mental and emotional experiences or perceptions does not prove that there must be any specific existence behind such a concept. We are succumbing to illusions produced by our self-created language, without reaching a better understanding of anything. Most of so-called philosophy is due to this kind of fallacy.
The self-styled practical man of affairs who pooh-poohs philosophy as a lot of windy notions is himself a pragmatist or a positivist, and a bad one at that, since he has given no thought to his position.
Nature in darkness groans and men are bound to sullen contemplation in the night: restless they turn on beds of sorrow; in their inmost brain feeling the crushing wheels, they rise, they write the bitter words of stern philosophy and knead the bread of knowledge with tears and groans.
Other people are likely not to be aware that those who pursue philosophy aright study nothing but dying and being dead. Now if this is true, it would be absurd to be eager for nothing but this all their lives, and then to be troubled when that came for which they had all along been eagerly practicing.
In youth it is the outward aspect of things that most engages us; while in age, thought or reflection is the predominating qualityof 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.
Now many such things may be done without intitling the people to rise in arms. A gross, flagrant, and palpable abuse no doubt will do it, as if they should be required to pay a tax equal to half or third of their substance.
The system of Descartes... seemed to give a plausible reason for all those phenomena; and this reason seemed more just, as it is simple and intelligible to all capacities. But in philosophy, a student ought to doubt of the things he fancies he understands too easily, as much as of those he does not understand.
That is what the highest criticism really is, the record of one's own soul. It is more fascinating than history, as it is concerned simply with oneself. It is more delightful than philosophy, as its subject is concrete and not abstract, real and not vague. It is the only civilized form of autobiography.
