You must know for yourself, directly, the truth of yourself and you cannot realize it through another, however great. There is no authority that can reveal it.
A good half of the effort of understanding what the Indian philosophers were after - and their subtleties make most of the great European philosophers look like schoolboys.
All the interests of my reason, speculative as well as practical, combine in the three following questions: 1. What can I know? 2. What ought I to do? 3. What may I hope?
He in whom the love of repose predominates will accept the first creed, the first philosophy, the first political party he meets — most likely his father's. He gets rest, commodity, and reputation; but he shuts the door of truth.
A philosophy which speaks, even indirectly, only to philosophers is no philosophy at all; and I think the same is true if it speaks only to scientists, or only to jurists, or priests, or any other special class.
Plato is philosophy, and philosophy, Plato,--at once the glory and the shame of mankind, since neither Saxon nor Roman have availed to add any idea to his categories.
To mix science up with philosophy is only to produce a philosophy that has lost all its ideal value and a science that has lost all its practical value. It is for my private physician to tell me whether this or that food will kill me. It is for my private philosopher to tell me whether I ought to be killed.
The philosopher believes that the value of his philosophy lies in the whole, in the building: posterity discovers it in the bricks with which he built and which are then often used again for better building: in the fact, that is to say, that building can be destroyed and nonetheless possess value as material.
A religion, that is, a true religion, must consist of ideas and facts both; not of ideas alone without facts, for then it would be mere Philosophy; - nor of facts alone without ideas, of which those facts are symbols, or out of which they arise, or upon which they are grounded: for then it would be mere History.
How I understand the philosopher - as a terrible explosive, endangering everthing... my concept of the philosopher is worlds removed from any concept that would include even a Kant, not to speak of academic "ruminants" and other professors of philosophy.
In raising the price of commodities, the rise of wages operates in the same manner as simple interest does in the accumulation of debt. Our merchants and master manufacturers complain much of the bad effects of high wages in raising the price, and thereby lessening the sale of their goods, both at home and abroad. They say nothing concerning the bad effects of high profits; they are silent with regard to the pernicious effects of their own gains. They complain only of those of other people.
More and more it seems to me that the philosopher, being of necessity a man of tomorrow and the day after tomorrow, has always found himself, and had to find himself, in contradiction to his today: his enemy was ever the ideal of today. So far all these extraordinary furtherers of men whom one calls philosophers, though they themselves have rarely felt like friends of wisdom but rather like disagreeable fools and dangerous question marks, have found their task, their hard, unwanted, inescapable task, but eventually also the greatness of their task, in being the bad conscience of their time.
