Scepticism, ironically, draws its life's blood from claims to have a good deal of knowledge. For example, your friends claim to know, 'Since every possible option has not been explored, nothing can be said for certain.' That statement is itself a claim to knowledge!

We must be sceptical even of our scepticism.
The three main sources of scepticism are first, that not every people desires freedom second, that democracy in certain parts of the world would be dangerous and third, that there is little the world's democracies can do to advance freedom outside their countries.
Nothing fortifies scepticism more than that there are some who are not sceptics; if all were so, they would be wrong.
Scepticism, like wisdom, springs out in full panoply only from the brain of a god, and it is little profit to see an idea in its growth, unless we track its seed to the power which sowed it.
There is but one indefectibly certain truth , and that is the truth that pyrrhonistic scepticism itself leaves standing, the truth that the present phenomenon of consciousness exists.
Scepticism is an ability, or mental attitude, which opposes appearances to judgments in any way whatsoever, with the result that,owing to the equipollence of the objects and reasons thus opposed we are brought firstly to a state of mental suspense and next to a state of "unperturbedness" or quietude.
A truth now and then projecting into the ocean of newspaper lies serves like headlands to correct our course. Indeed, my scepticism as to everything I see in a newspaper makes me indifferent whether I ever see one.
And, as soon as possible, be on the lookout for someone whose whole manner of speaking and being makes, as it were, a "sound" that draws your mind and heart. And then, little by little, try to see if that person can be of real help on the way to genuine self-knowledge and insight about what God is and is not. In this realm, more than any other even, the paradoxical marriage of both openness and scepticism is essential.
A thing is not proved just because no one has ever questioned it. What has never been gone into impartially has never been properly gone into. Hence scepticism is the first step toward truth. It must be applied generally, because it is the touchstone.
Scepticism is the first step towards truth.
Scepticism is the beginning of Faith.
In all the events of life, we ought still to preserve our scepticism. If we believe that fire warms, or water refreshes, it is only because it costs us too much pains to think otherwise.
Scepticism and refusal of authority is at the heart of scientific endeavour. Scientific knowledge dictates economic possibilities
Scepticism, that dry caries of the intelligence.
It is quite an old-fashioned fallacy to suppose that our objection to scepticism is that it removes the discipline from life. Our objection to scepticism is that it removes the motive power. Materialism is not a thing which destroys mere restraint. Materialism itself is the great restraint.
I dip my pen in the blackest ink, because I'm not afraid of falling into my inkpot.
A just thinker will allow full swing to his scepticism. I dip my pen in the blackest ink, because I am not afraid of falling into my inkpot.... We are of different opinions at different hours, but we always may be said to be at heart on the side of truth.
We are of different opinions at different hours, but we always may be said to be at heart on the side of truth.
The history of science alone can keep the physicist from the mad ambitions of dogmatism as well as the despair of pyrrhonian scepticism.
The scepticism which men affect towards their higher inspirations is often not an honest doubt, but a guilty negligence, and is a sign of narrow mind and defective wisdom.
I find that the critics of voluntary service are all too often those who are prepared to accept such services when they require them but deride them with cynicism and scepticism when they see others helping and being helped.
This scepticism is the same scepticism I heard a generation ago in the USSR when few thought that a democratic transformation behind the iron curtain was possible.
A rational reaction against the irrational excesses and vagaries of scepticism may, I admit, readily degenerate into the rival folly of credulity. To be engaged in opposing wrong affords, under the conditions of our mental constitution, but a slender guarantee for being right.
The path of sound credence is through the thick forest of skepticism.
It seems certain, that though a man, in a flush of humour, after intense reflection on the many contradictions and imperfections of human reason, may entirely renounce all belief and opinion, it is impossible for him to persevere in this total scepticism, or make it appear in his conduct for a few hours.
Each new ontological theory, propounded in lieu of previous ones shown to be untenable, has been followed by a new criticism leading to a new scepticism. All possible conceptions have been one by one tried and found wanting; and so the entire field of speculation has been gradually exhausted without positive result: the only result reached being the negative one above stated, that the reality existing behind all appearances is, and must ever be, unknown.
Before the 3rd century you're having several philosophical schools still as a going concern. You have not only the Platonists and the Aristotelians but you have Scepticism, you have Stoicism, you even have a little bit of Epicureanism. And what happens after Plotinus is that everybody becomes a Neo-Platonist. So if we then go forward to the Islamic world for example, Plotinus is immensely influential, and Neo-Platonism becomes at least one major component of mainstream Islamic philosophy as well.
The human understanding is a revelation from its maker, which can never be disputed or doubted. There can be no scepticism, Pyrrhonism, or incredulity or infidelity here. No prophecies, no miracles are necessary to prove this celestical communication. This revelation has made it certain that two and one make three, and that one is not three nor can three be one. We can never be so certain of any prophecy, or the fulfilment of any prophecy, or of any miracle, or the design of any miracle, as we are from the revelation of nature, that is, nature's God, that two and two are equal to four.
Discourses on humility are a source of pride in the vain and of humility in the humble. So those on scepticism cause believers to affirm. Few men speak humbly of humility, chastely of chastity, few doubtingly of scepticism.
It is true that 'I seem to see a table' does not entail 'I see a table'; but 'I seem to feel a pain' does entail 'I feel a pain'. So scepticism loses its force - cannot open up its characteristic gap - with regard to that which ultimately most concerns us, pleasure and pain.
No conclusions can be more agreeable to scepticism than such as make discoveries concerning the weakness and narrow limits of human reason and capacity.
Latter-day scepticism is fond of calling itself progressive; but scepticism is really reactionary. Scepticism goes back; it attempts to unsettle what has already been settled. Instead of trying to break up new fields with its plough, it simply tries to break up the plough.
The cause which is blocking all progress today is the subtle scepticism which whispers in a million ears that things are not good enough to be worth improving. If the world is good we are revolutionaries, if the world is evil we must be conservatives. These essays, futile as they are considered as serious literature, are yet ethically sincere, since they seek to remind men that things must be loved first and improved afterwards.
Scepticism is a necessary and vital part of the journalist's toolkit. But when scepticism becomes cynicism it can close off thought and block the search for truth.
What's the greatest enemy of Christianity to-day? Frozen meat. In the past only members of the upper classes were thoroughly sceptical, despairing, negative. Why? Among other reasons, because they were the only people who could afford to eat too much meat. Now there's cheap Canterbury lamb and Argentine chilled beef. Even the poor can afford to poison themselves into complete scepticism and despair.
Scepticism is a barren coast, without a harbor or lighthouse.
Scepticism is always a back road leading to some credo or other.
She believed in nothing; only her skepticism kept her from being an atheist.
In the way that scepticism is sometimes applied to issues of public concern, there is a tendency to belittle, to condescend, to ignore the fact that, deluded or not, supporters of superstition and pseudoscience are human beings with real feelings, who, like the sceptics, are trying to figure out how the world works and what our role in it might be. Their motives are in many cases consonant with science. If their culture has not given them all the tools they need to pursue this great quest, let us temper our criticism with kindness. None of us comes fully equipped.
Philosophy arises from an unusually obstinate attempt to arrive at real knowledge. What passes for knowledge in ordinary life suffers from three defects: it is cocksure, vague and self-contradictory. The first step towards philosophy consists in becoming aware of these defects, not in order to rest content with a lazy scepticism, but in order to substitute an amended kind of knowledge which shall be tentative, precise and self-consistent.
As its best, SF is the medium in which our miserable certainty that tomorrow will be different from today in ways we cant predict, can be transmuted to a sense of excitement and anticipation, occasionally evolving into awe. Poised between intransigent scepticism and uncritical credulity, it is par excellence the literature of the open mind.
Major problem for Black women, and all people of color, when we are challenged to oppose anti-Semitism, is our profound skepticism that white people can actually be oppressed.
The average businessman began to be agnostic, not so much because he did not know where he was, as because he wanted to forget. Many of the rich took to scepticism exactly as the poor took to drink; because it was a way out.
Scepticism is effortful and costly. It is better to be sceptical about matters of large consequences, and be imperfect, foolish and human in the small and the aesthetic.
And indeed nothing but the most determined scepticism, along with a great degree of indolence, can justify this aversion to metaphysics. For if truth be at all within the reach of human capacity, it is certain it must lie very deep and abstruse: and to hope we shall arrive at it without pains, while the greatest geniuses have failed with the utmost pains, must certainly be esteemed sufficiently vain and presumptuous. I pretend to no such advantage in the philosophy I am going to unfold, and would esteem it a strong presumption against it, were it so very easy and obvious.
If you are only skeptical, then no new ideas make it through to you.
Healthy scepticism is the basis of all accurate observation.
Thank God for that. You can shut them, say, 'Hold on a moment.' You play God to it. But who has ever torn himself from the claw that encloses you when you drop a seed in a TV parlour? It grows you any shape it wishes! It is an environment as real as the world. It becomes and is the truth. Books can be beaten down with reason. But with all my knowledge and scepticism, I have never been able to argue with a one-hundred-piece symphony orchestra, full colour, three dimensions, and I being in and part of those incredible parlours.
If we offer too much silent assent about mysticism and superstition - even when it seems to be doing a little good - we abet a general climate in which scepticism is considered impolite, science tiresome, and rigorous thinking somehow stuffy and inappropriate.
