Whatever torch we kindle, and whatever space it may illuminate, our horizon will always remain encircled by the depth of night.

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.

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.

Every new born being indeed comes fresh and blithe into the new existence, and enjoys it as a free gift: but there is, and can be, nothing freely given.

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.
