Christianity asserts that every individual human being is going to live for ever, and this must be either true or false. Now there are a good many things which would not be worth bothering about if I were going to live only seventy years, but which I had better bother about very seriously if I am going to live for ever.
C. S. Lewis

If 'god' is a metaphysical term, then it cannot be even probable that a god exists. For to say that 'God exists' is to make a metaphysical utterance which cannot be either true or false. And by the same criterion, no sentence which purports to describe the nature of a transcendent god can possess any literal significance.
A.J. Ayer
3.
Every sentence in order to have definite scientific meaning must be practically or at least theoretically verifiable as either true or false upon the basis of experimental measurements either practically or theoretically obtainable by carrying out a definite and previously specified operation in the future. The meaning of such a sentence is the method of its verification.
Walter A. Shewhart

Nothing in the world, no object or event, would be true or false if there were not thinking creatures.
Donald Davidson
5.
Its guilt therefore in these cases, is not to be measure by its effects on the happiness of mankind; nor is it to be denominated true or false glory, accordingly as the ends to which it is directed are beneficial or mischievous, just or unjust objects of pursuit; but it is false, because it exalts that which ought to be abased, and criminal, because it encroaches on the prerogative of God.
William Wilberforce
6.
The meaning of the presupposition is the method of verification… we know the meaning of the statement if we know the conditions under which the statement is true or false.
Moritz Schlick
7.
One comes to believe whatever one repeats to oneself sufficiently often, whether the statement be true or false.
Robert Collier
8.
The wrong question to ask of a myth is whether it is true or false. The right question is whether it is living or dead, whether it still speaks to our condition.
Richard Holloway
9.
Don't forget that few people are likely to tell more than a small part of the truth: no one tells much of the truth, let alone the whole truth. Spoken words are facts in themselves, whether true or false. When people talk they reveal themselves, whether they're lying or telling the truth.
Halldór Laxness
10.
Plots, true or false, are necessary things, To raise up commonwealths and ruin kings.
John Dryden
11.
If you believe certain words, you believe their hidden arguments. When you believe something is right or wrong, true or false, you believe the assumptions in the words which express the arguments. Such assumptions are often full of holes, but remain most precious to the convinced.
Frank Herbert
12.
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.
Thomas Huxley
13.
What signifies protesting so against flattery when a person speaks well of one, it must either be true or false, you know if true, let us rejoice in his good opinion if he lies, it is a proof at least that he loves more to please me, than to sit s
Samuel Johnson

There are no hard distinctions between what is real and what is unreal, nor between what is true and what is false. A thing is not necessarily either true or false; it can be both true and false.
Harold Pinter

The statesman cannot govern without stability of belief, true or false.
George Bernard Shaw

Sentences are not as such either true or false.
J. L. Austin
17.
Good and evil are essential differences of the act of the will. For good and evil pertain essentially to the will; just as truth and falsehood pertain to the reason, the act of which is distinguished essentially by the difference of truth and falsehood (according as we say that an opinion is true or false.) Consequently, good and evil volition are acts differing in species.
Thomas Aquinas
18.
Everywhere there is apathy. Nobody cares whether that which is preached is true or false. A sermon is a sermon whatever the subject; only, the shorter it is, the better.
Charles Spurgeon
19.
The public read newspapers, see television, they watch, they don't know if it's true or false because they're not involved.
Donald Trump
20.
Martyrdom, as a rule, establishes the sincerity of the martyr, never the correctness of his thought. Things are true or false in themselves.
Robert Green Ingersoll
21.
But lest I should mislead any when I have my own head and obey my whims, let me remind the reader that I am only an experimenter.Do not set the least value on what I do, or the least discredit on what I do not, as if I pretended to settle any thing as true or false. I unsettle all things. No facts are to me sacred; none are profane; I simply experiment, an endless seeker with no Past at my back.
Ralph Waldo Emerson
22.
Here are the three great questions which in life we have over and over again to answer: Is it right or wrong? Is it true or false? Is it beautiful or ugly? Our education ought to help us to answer these questions.
John Lubbock
23.
You can talk about a caption underneath a photograph being true or false, because there is a linguistic element. You can claim that a photograph is a picture of a horse or a cow, but it is the sentence that expresses the claim, which is true or false, not the photograph.
Errol Morris

Aphorisms are not true or false, but pointed or flat.
Mason Cooley

Whether this tale be true or false, none can tell, for none were there to witness it themselves.
Marjane Satrapi

I don't believe that you can talk about a photograph being true or false. I don't think such a claim has any meaning.
Errol Morris

I'll give anything for a good copy now, be it true or false, so it be news.
Ben Jonson
31.
The reporting is fake. Look, look...You know what it is? Here's the thing. The public isn't - you know, they read newspapers, they see television, they watch. They don't know if it's true or false because they're not involved.But I'm involved. So I know when you're telling the truth or when you're not. I just see many, many untruthful things.
Kevin Drum

The intensity of a conviction that a hypothesis is true has no bearing on whether it is true or false. The importance of the strength of our conviction is only to provide a proportionately strong incentive to find out if the hypothesis will stand up to critical evaluation.
Peter Medawar
