John Locke Quotes

If faith is a valid tool of knowledge, then anything can be true 'by faith,' and therefore nothing is true. If the only reason you can accept a claim is by faith, then you are admitting that the claim does not stand on its own merits.

For nothing ought to be posited without a reason given, unless it is self-evident (literally, known through itself) or known by experience or proved by the authority of Sacred Scripture.

It would be superfluous to receive by faith, things that can be known by natural reason

Revelation in matters where reason cannot judge, or but probably, ought to be hearkened to. First, Whatever proposition is revealed, of whose truth our mind, by its natural faculties and notions, cannot judge, that is purely matter of faith, and above reason.

Power is not sufficient evidence of truth.

After a long, impartial enquiry of the truth, and after much and earnest calling upon God, to give unto me the spirit and revelation in the knowledge of Him, I find myself obliged, both by the principles of reason and Scripture, to embrace the opinion I now hold forth.

If all you have is faith, then you never actually know anything.

Our reason arises, at the very least, from this twofold lesson of sensuous revelations and human testimonies.

Science stands for rational thought, faith for superstition and unreason.

I do not feel obliged to believe that the same God who has endowed us with senses, reason and intellect has intended us to forego their use and by some other means to give us knowledge which we can attain by them.

We honor revelation too highly to make it the antagonist of reason, or to believe that it calls us to renounce our highest powers.

[It's] troubling because it reminds us how difficult it is to prove anything. We like to pretend that our experiments define the truth for us. But that's often not the case. Just because an idea is true doesn't mean it can be proved. And just because an idea can be proved doesn't mean it's true. When the experiments are done, we still have to choose what to believe.

As the telescope is not a substitute for, but an aid to, our sight, so revelation is not designed to supersede the use of reason, but to supply its deficiencies.

On the road halfway between faith and criticism stands the inn of reason. Reason is faith in what can be understood without faith, but it's still a faith, since to understand presupposes that there's something understandable.

It is easy to see, though it scarcely needs to be pointed out, since it is involved in the fact that Reason is set aside, that faith is not a form of knowledge; for all knowledge is either a knowledge of the eternal, excluding the temporal and historical as indifferent, or it is pure historical knowledge. No knowledge can have for its object the absurdity that the eternal is the historical.

There are those, of course, who deny that they need any form of authority. They are the popular atheists and agnostics. Such men say that they must be shown by 'reason' whatever they are to accept as true. But the great thinkers among non-Christian men have taken no such position. They know that they cannot cover the whole area of reality with their knowledge.

Faith is the commitment of one's consciousness to beliefs for which one has no sensory evidence or rational proof. When man rejects reason as his standard of judgement, only one alternative standard remains to him: his feelings. A mystic is a man who treats his feelings as tools of cognition. Faith is the equation of feelings with knowledge

Believing things on authority only means believing them because you have been told them by someone you think trustworthy. Ninety-nine per cent of the things you believe are believed on authority... Every historical event in the world is believed on authority. None of us has seen the Norman Conquest or the defeat of the Armada.

The agnostic does not simply say, "l do not know." He goes another step, and he says, with great emphasis, that you do not know. He insists that you are trading on the ignorance of others, and on the fear of others. He is not satisfied with saying that you do not know, -- he demonstrates that you do not know, and he drives you from the field of fact -- he drives you from the realm of reason -- he drives you from the light, into the darkness of conjecture -- into the world of dreams and shadows, and he compels you to say, at last, that your faith has no foundation in fact.

Reason is natural revelation, whereby the eternal father of light, and fountain of all knowledge, communicates to mankind that portion of truth which he has laid within the reach of their natural faculties: revelation is natural reason enlarged by a new set of discoveries communicated by God. . . .

All men are capable of reason. That is the fundamental principle of democracy Because everybody's mind is capable of true knowledge, you don't have to have a special authority, or a special revelation telling you that this is the way things should be.

God forbid that Truth should be confined to Mathematical Demonstration!

You can only find truth with logic if you have already found truth without it.

...I will not allow books to prove any thing." "But how shall we prove any thing?" "We never shall.

I ask the fundamental question of rationality: Why do you believe what you believe? What do you think you know and how do you think you know it?
