Let me tell you something big: Give importance to little things!

However infinite the Universe may be, our true and practical universe is still the surroundings of the house we live in.

To enlighten people by reminding them the irrationality of their beliefs is an act more honest and more important than the act of praising and respecting people's beliefs!

Seek not a lighthouse greater than the human mind! Believe not the existence of an emotion nobler than the compassion!

My dear friend, to be both powerful and fair has always been difficult for mankind. Power and justice have always been seen like day and night; this being the case, when one of them is there the other disappears.

We can't see and we can't reach the frontiers of our ignorance; we can only approach to it by extending our knowledge.

This world has a secret rule: Those who have to die live, and those who have to live die!
