Blind belief in authority is the greatest enemy of truth.

A foolish faith in authority is the worst enemy of truth.

Somebody who only reads newspapers and at best books of contemporary authors looks to me like an extremely near-sighted person who scorns eyeglasses. He is completely dependent on the prejudices and fashions of his times, since he never gets to see or hear anything else.

I want to oppose the idea that the school has to teach directly that special knowledge and those accomplishments which one has to use later directly in life. The demands of life are much too manifold to let such a specialized training in school appear possible [...] The development of general ability for independent thinking and judgement should always be placed foremost.

It is the first responsibility of every citizen to question authority.

I do this real moron thing, and it's called thinking. And apparently I'm not a very good American because I like to form my own opinions.
