The improver of natural knowledge absolutely refuses to acknowledge authority, as such. For him, skepticism is the highest of duties; blind faith the one unpardonable sin.

Some suggestions for you :

I am too much of a skeptic to deny the possibility of anything.

It is one of the most saddening things in life that, try as we may, we can never be certain of making people happy, whereas we can almost always be certain of making them unhappy.

Time, whose tooth gnaws away everything else, is powerless against truth.

The only medicine for suffering, crime, and all other woes of mankind, is wisdom. Teach a man to read and write, and you have put into his hands the great keys of the wisdom box. But it is quite another thing to open the box.

Science and literature are not two things, but two sides of one thing.

The only question which any wise man can ask himself, and which any honest man will ask himself, is whether a doctrine is true or false.

The rung of a ladder was never meant to rest upon, but only to hold a man's foot long enough to enable him to put the other somewhat higher.

Patience and tenacity of purpose are worth more than twice their weight of cleverness.

Only one absolute certainty is possible to man namely that at any given moment the feeling which he has exists.

I took thought, and invented what I conceived to be the appropriate title of 'agnostic'.

I protest that if some great Power would agree to make me always think what is true and do what is right, on condition of being turned into a sort of clock and would up every morning before I got out of bed, I should instantly close with the offer.

Science is nothing, but trained and organized common sense.

I am content with nothing, restless and ambitious... and I despise myself for the vanity, which formed half the stimulus to my exertions. Oh would that I were one of those plodding wise fools who having once set their hand to the plough go on nothing doubting.

Size is not grandeur, and territory does not make a nation.
