Do not believe in anything simply because you have heard it. Do not believe in anything simply because it is spoken and rumored by many. Do not believe in anything simply because it is found written in your religious books. Do not believe in anything merely on the authority of your teachers and elders. Do not believe in traditions because they have been handed down for many generations. But after observation and analysis, when you find that anything agrees with reason and is conducive to the good and benefit of one and all, then accept it and live up to it.
In questions of science, the authority of a thousand is not worth the humble reasoning of a single individual.
Science cannot solve the ultimate mystery of nature. And that is because, in the last analysis, we ourselves are a part of the mystery that we are trying to solve.

It vexes me when they would constrain science by the authority of the Scriptures, and yet do not consider themselves bound to answer reason and experiment.
I was bold in the pursuit of knowledge, never fearing to follow truth and reason to whatever results they led, and bearding every authority which stood in their way.

The generous Critic fann'd the Poet's fire, And taught the world with reason to admire.
And sometimes I'm criticized. But I think that if those who criticize us will look at the reason why the shape is this, well then, I think that they would not object so strenuously.
I've been criticized for not having perspective in the past and I thought that of myself many times but not there.
Literature is strewn with the wreckage of men who have minded beyond reason the opinions of others.
I've lost many of my best friends... I'm going to satisfy myself now, not the critics, not even my friends.
I prefer rogues to imbeciles, because they sometimes take a rest.

The most beautiful things are those that madness prompts and reason writes.
Government is an association of men who do violence to the rest of us.
A fact is like a sack - it won't stand up if it's empty. To make it stand up, first you have to put in it all the reasons and feelings that caused it in the first place.
The whole theory of the universe is directed unerringly to one single individual.
If we long to believe that the stars rise and set for us, that we are the reason there is a Universe, does science do us a disservice in deflating our conceits?
Eroticism has its own moral justification because it says that pleasure is enough for me; it is a statement of the individual's sovereignty.
The important thing is not to stop questioning. Curiosity has its own reason for existing.
