They lied to you. The Devil is not the Prince of Matter; the Devil is the arrogance of the spirit, faith without smile, truth that is never seized by doubt. The Devil is grim because he knows where he is going, and, in moving, he always returns whence he came.

Where men are the most sure and arrogant, they are commonly the most mistaken, and have there given reins to passion, without that proper deliberation and suspense, which can alone secure them from the grossest absurdities.
David Hume (1711-1776) Scottish philosopher, economist, historian, empiricist
An Enquiry Concerning the Principles of Morals, Sec. 9.13 “Conclusion, Pt. 1” (1751)
The essence of the Liberal outlook lies not in what opinions are held, but in how they are held: instead of being held dogmatically, they are held tentatively, and with a consciousness that new evidence may at any moment lead to their abandonment.

Our new Constitution is now established, and has an appearance that promises permanency, but in this world nothing can be said to be certain, except death and taxes.
Not that indeed I imitated the sceptics, who only doubt for the sake of doubting, and pretend to be always uncertain; for, on the contrary, my design was only to provide myself with good ground for assurance, and to reject the quicksand and mud in order to find the rock or clay.
[Non que j’imitasse pour cela les sceptiques, qui ne doutent que pour douter, et affectent d’être toujours irrésolus; car, au contraire, tout mon dessein ne tendoit qu’à m’assurer, et à rejeter la terre mouvante et le sable pour trouver le roc ou l’argile.]

Not that I therein imitated the Scepticks, who doubt onely to the end they may doubt, and affect to be always unresolved: For on the contrary, all my designe tended onely to fix my self, and to avoid quick-mires and sands, that I might finde rock and clay.
[tr. Newcombe ed. (1649)]
Not that in this I imitated the sceptics who doubt only that they may doubt, and seek nothing beyond uncertainty itself; for, on the contrary, my design was singly to find ground of assurance, and cast aside the loose earth and sand, that I might reach the rock or the clay.
[tr. Veitch (1901)]
For all that, I did not imitate the sceptics who doubt only for doubting's sake, and pretend to be always undecided; on the contrary, my whole intention was to arrive at a certainty, and to dig away the drift and the sand until I reached the rock or the clay beneath.
[tr. Huxley (1870)]
In doing this I was not copying the sceptics, who doubt only for the sake of doubting and pretend to be always undecided; on the contrary, my whole aim was to reach certainty -- to cast aside the loose earth and sand so as to come upon rock or clay.

To refuse a hearing to an opinion because they are sure that it is false, is to assume that their certainty is the same thing as absolute certainty. All silencing of discussion is an assumption of infallibility.

Certitude is not the test of certainty. We have been cocksure of many things that were not so.

It is this belief in absolutes, I would hazard, that is the great enemy today of the life of the mind. This may seem a rash proposition. The fashion of the time is to denounce relativism as the root of all evil. But history suggests that the damage done to humanity by the relativist is far less than the damage done by the absolutist — by the fellow who, as Mr. Dooley once put it, “does what he thinks th’ Lord wud do if He only knew th’ facts in th’ case.”

To be effective a doctrine must not be understood, but has to be believed in. We can be absolutely certain only about things we do not understand. A doctrine that is understood is shorn of its strength.

Isn’t it the moment of most profound doubt that gives birth to new certainties? Perhaps hopelessness is the very soil that nourished human hope; perhaps one could never find sense in life without first experiencing its absurdity.

Not to be absolutely certain is, I think, one of the essential things in rationality.

Moral certainty is always a sign of cultural inferiority. The more uncivilized a man, the surer he is that he knows precisely what is right and what is wrong. All human progress, even in morals, has been the work of men who have doubted the current moral values, not of men who have whooped them up and tried to enforce them. The truly civilized man is always skeptical and tolerant in this field as in all others. His culture is based on “I am not too sure.”

Agnosticism is not properly described as a “negative” creed, nor indeed as a creed of any kind, except in so far as it expresses absolute faith in the validity of a principle which is as much ethical as intellectual. This principle may be stated in various ways, but they all amount to this: that it is wrong for a man to say that he is certain of the objective truth of any proposition unless he can produce evidence which logically justifies that certainty. This is what Agnosticism asserts; and, in my opinion, it is all that is essential to Agnosticism.

Too much positive is either scared or stupid or both. Reality is uncertain.
Robert B. Parker (1932-2010) American writer
Early Autumn (1981)
The causes of the Great Depression are still far from certain. A lack of certainty, it may also be observed, is not evident in the contemporary writing on the subject. Much of it tells what went wrong and why with marked firmness. However, this paradoxically can itself be an indication of uncertainty. When people are least sure they are often most dogmatic.

The spirit of liberty is the spirit which is not too sure that it is right; the spirit of liberty is the spirit which seeks to understand the mind of other men and women; the spirit of liberty is the spirit which weighs their interests alongside its own without bias; the spirit of liberty remembers that not even a sparrow falls to earth unheeded; the spirit of liberty is the spirit of Him who, near two thousand years ago, taught mankind that lesson it has never learned but never quite forgotten; that there may be a kingdom where the least shall be heard and considered side by side with the greatest.
