Nothing leads so straight to futility as literary ambitions without systematic knowledge.

True knowledge exists in knowing that you know nothing.

All our knowledge begins with the senses proceeds then to the understanding and ends with reason. There is nothing higher than reason.

To know is to know that you know nothing. That is the meaning of true knowledge.

No man can reveal to you nothing but that which already lies half-asleep in the dawning of your knowledge.

He who knows nothing is closer to the truth than he whose mind is filled with falsehoods and errors.

Serious sport has nothing to do with fair play. It is bound up with hatred jealousy boastfulness disregard of all rules and sadistic pleasure in witnessing violence. In other words it is war minus the shooting.

To jealousy nothing is more frightful than laughter.

Guard with jealous attention the public liberty. Suspect everyone who approaches that jewel. Unfortunately nothing will preserve it but downright force. Whenever you give up that force you are inevitably ruined.

God gives us intelligence to uncover the wonders of nature. Without the gift nothing is possible.

Intelligence is nothing without delight.

Nothing has caused the human race so much trouble as intelligence.

Of course I believe in aliens. I think it's very egocentric to think that there's nothing else with intelligence in the whole universe.

Undernourished intelligence becomes like the bloated belly of a starving child: swollen filled with nothing the body can use.

There is no greater evidence of superior intelligence than to be surprised at nothing.

I know that I am intelligent because I know that I know nothing.

Nothing makes one feel so strong as a call for help.
