The scenes of our life are like pictures done in rough mosaic. Looked at close, they produce no effect. There is nothing beautiful to be found in them, unless you stand some distance off.
Descartes is rightly regarded as the father of modern philosophy primarily and generally because he helped the faculty of reason to stand on its own feet by teaching men to use their brains
in place whereof the Bible, on the one hand, and Aristotle, on the other, had previously served.
Nothing in life gives a man so much courage as the attainment or renewal of the conviction that other people regard him with favor; because it means that everyone joins to give him help and protection, which is an infinitely stronger bulwark against the ills of life than anything he can do himself.
To free a man from error is to give, not to take away. Knowledge that a thing is false is a truth. Error always does harm; sooner or later it will bring mischief to the man who harbors it.
No greater mistake can be made than to imagine that what has been written latest is always the more correct; that what is written later on is an improvement on what was written previously; and that every change means progress.
With health, everything is a source of pleasure; without it, nothing else, whatever it may be, is enjoyable...Healt h is by far the most important element in human happiness.
To form a judgment intuitively is the privilege of few; authority and example lead the rest of the world. They see with the eyes of others, they hear with the ears of others. Therefore it is very easy to think as all the world now think; but to think as all the world will think thirty years hence is not in the power of every one.
Ist es an und fu? r sich absurd, das Nichtsein fu? r einUbel zu ? halten; da jedes Ubel wie jedes Gut das Dasein zur Voraussetzung hat, ja sogar das Bewusstsein. It is in and by itself absurd to regard non-existence as an evil; for every evil, like every good, presupposes existence, indeed even consciousness.
Consciousness makes the individual careful to maintain his own existence; and if this were not so, there would be no surety for the preservation of the species. From all this it is clear that individuality is not a form of perfection, but rather a limitation; and so to be freed from it is not loss but gain.
As the biggest library if it is in disorder is not as useful as a small but well-arranged one, so you may accumulate a vast amount of knowledge but it will be of far less value to you than a much smaller amount if you have not thought it over for yourself; because only through ordering what you know by comparing every truth with every other truth can you take complete possession of your knowledge and get it into your power. You can think about only what you know, so you ought to learn something; on the other hand, you can know only what you have thought about.
