I think nobody should be certain of anything. If you’re certain, you’re certainly wrong, because nothing deserves certainty, and so one ought always to hold all one’s beliefs with a certain element of doubt and one ought to be able to act vigorously in spite of the doubt.

Our secularism is hard-won, the product of centuries of political, intellectual, and sometimes physical courage. Secularism is the institutionalization of doubt, or more precisely of respect for doubt. It is harder to love doubt than to love freedom. So we are grudging about our secularism, and some of us are a little ashamed of it. Maybe it takes Rushdie’s nightmare and Khomeini’s rage to remind us how precious it is, and how fiercely it must be guarded.

Inquiry into the evidence of a doctrine is not to be made once for all, and then taken as finally settled. It is never lawful to stifle a doubt; for either it can be honestly answered by means of the inquiry already made, or else it proves that the inquiry was not complete.
“But,” says one, “I am a busy man; I have no time for the long course of study which would be necessary to make me in any degree a competent judge of certain questions, or even able to understand the nature of the arguments.” Then he should have no time to believe.

Every time we let ourselves believe for unworthy reasons, we weaken our powers of self-control, of doubting, of judicially and fairly weighing evidence. We all suffer severely enough from the maintenance and support of false beliefs and the fatally wrong actions which they lead to, and the evil born when one such belief is entertained is great and wide. But a greater and wider evil arises when the credulous character is maintained and supported, when a habit of believing for unworthy reasons is fostered and made permanent.

To know all about anything is to know how to deal with it under all circumstances. We feel much happier and more secure when we think we know precisely what to do, no matter what happens, than when we have lost our way and do not know where to turn. And if we have supposed ourselves to know all about anything, and to be capable of doing what is fit in regard to it, we naturally do not like to find that we are really ignorant and powerless, that we have to begin again at the beginning, and try to learn what the thing is and how it is to be dealt with — if indeed anything can be learnt about it. It is the sense of power attached to a sense of knowledge that makes men desirous of believing, and afraid of doubting.

You must have three essentials for the investigation of Chan [Zen]. The first is that you must have the foundation of great faith. The second is that you must have a zealous determination.

It would never come into their [the masses’] heads to fabricate colossal untruths, and they would not believe that others could have the impudence to distort the truth so infamously. Even though the facts which prove this to be so may be brought clearly to their minds, they will still doubt and waver and will continue to think that there may be some other explanation. For the grossly impudent lie always leaves traces behind it, even after it has been nailed down, a fact which is known to all expert liars in this world and to all who conspire together in the art of lying.
The dividing line between those who want to think and therefore have to judge by themselves, and those who do not, strikes across all social and cultural or educational differences. In this respect, the total moral collapse of respectable society during the Hitler regime may teach us that under such circumstances those who cherish values and hold fast to moral norms and standards are not reliable: we now know that moral norms and standards can be changed overnight, and that all that then will be left is the mere habit of holding fast to something. Much more reliable will be the doubters and skeptics, not because skepticism is good or doubting wholesome, but because they are used to examine things and to make up their own minds. Best of all will be those who know only one thing for certain: that whatever else happens, as long as we live we shall have to live together with ourselves.

If a man has a genuine, sincere, hearty wish to get rid of his liberty, if he is really bent upon becoming a slave, nothing can stop him. And the temptation is to some natures a very great one. Liberty is often a heavy burden on a man. It involves that necessity for perpetual choice which is the kind of labor men have always dreaded. In common life we shirk it by forming habits, which take the place of self-determination. In politics party-organization saves us the pains of much thinking before deciding how to cast our vote. In religious matters there are great multitudes watching us perpetually, each propagandist ready with his bundle of finalities, which having accepted we may be at peace. The more absolute the submission demanded, the stronger the temptation becomes to those who have been long tossed among doubts and conflicts.

Progress generally begins in skepticism about accepted truths. Intellectual freedom means the right to reexamine much that has been long taken for granted. A free man must be a reasoning man, and he must dare to doubt what a legislative or electoral majority may most passionately assert. The danger that citizens will think wrongly is serious, but less dangerous than atrophy from not thinking at all.

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.”

Sufficient to today are the duties of today. Don’t waste life in doubts and fears; spend yourself on the work before you, well assured that the right performance of this hour’s duties will be the best preparation for the hours and ages that will follow it.
Ralph Waldo Emerson (1803-1882) American essayist, lecturer, poet
“Immortality,” Letters and Social Aims (1876)
