Prove it. I'll measure your words against your actions, and from that I will determine your worth.

Live your own truth and it won't matter how many lies they tell about you. The truth will prove itself.

I have carefully examined the evidences of the Christian religion, and if I was sitting as a juror upon its authenticity I would unhesitatingly give my verdict in its favor. I can prove its truth as clearly as any proposition ever submitted to the mind of man.

It is with logic that one proves; it is with intuition that one invents.

All this could be part of a plan. There is no way an atheist can prove it’s not. But it’s some plan, isn't it? With mass destruction, pitiless extermination, annihilation going on all the time. And all of this set in motion on a scale that’s absolutely beyond our imagination, in order that the pope can tell people not to jerk off.

Hollywood sucks. I've got the bruises to prove it.

Every great discovery I ever made, I gambled that the truth was there, and then I acted in faith until I could prove its existence.

But the Chief Justice says, 'There must be an ultimate arbiter somewhere.' True, there must; but does that prove it is either party? The ultimate arbiter is the people of the Union, assembled by their deputies in convention, at the call of Congress or of two-thirds of the States. Let them decide to which they mean to give an authority claimed by two of their organs. And it has been the peculiar wisdom and felicity of our Constitution, to have provided this peaceable appeal, where that of other nations is at once to force.

Smearing good people like Lauchlin Currie [former administrative assistant to President Roosevelt], Alger Hiss and others is, I think, unforgiveable... Anyone knowing Mr. Currie or Mr. Hiss, who are the two people whom I happen to know fairly well, would not need any denial on their part to know they are not Communists. Their records prove it.

The fact that The Bridge contains folk lore and other material suitable to the epic form need not therefore prove its failure as a long lyric poem, with interrelated sections.

You think you're an artist; prove it

The homestead policy was established only after long and earnest resistance; experience proves its wisdom. The lands in the hands of industrious settlers, whose labor creates wealth and contributes to the public resources, are worth more to the United States than if they had been reserved as a solitude for future purchasers.

No number of sightings of white swans can prove the theory that all swans are white. The sighting of just one black one may disprove it.

I can't prove it, but I can say it.

A good conspiracy is unprovable. I mean, if you can prove it, it means they screwed up somewhere along the line.

I simply imagine it so, then go about to prove it.

You haven't learned life's lesson very well if you haven't noticed that you can give the tone or colour, or decide the reaction you want of people in advance. It's unbelievable simply. If you want them to take an interest in you, take an interest in them first. If you want to make them nervous, become nervous yourself...It's as simple as that. People will treat you as you treat them. It's no secret. Look about you. You can prove it with the next person you meet.

Any physical theory is always provisional, in the sense that it is only a hypothesis: you can never prove it.
