When you have desires to do something wrong, you might feel so embarrassed with yourself for not being on a higher level that you try to repress those desires and forget about them. This is a mistake since it is not dealing with the problem but covering it up. Ignoring your inner feelings and reactions is dangerous. Be aware of what you desire, and have a dialogue with yourself to overcome it.

Incredulity is not wisdom, but the worst kind of folly. It is folly, because it causes ignorance and mistake, with all the consequents of these; and it is very bad, as being accompanied with disingenuity, obstinacy, rudeness, uncharitableness, and the like, bad dispositions; from which credulity itself, the other extreme sort of folly, is exempt.

It is a very easy thing to devise good laws; the difficulty is to make them effective. The great mistake is that of looking upon men as virtuous, or thinking that they can be made so by laws; and consequently the greatest art of a politician is to render vices serviceable to the cause of virtue.

From a worldly point of view there is no mistake so great as that of being always right.

Mistake, error, is the discipline through which we advance.

The very nearest approach to domestic happiness on earth is in the cultivation on both sides of absolute unselfishness. Never both be angry at once. Never talk at one another, either alone or in company. Never speak loud to one another unless the house is on fire. Let each; one strive to yield oftenest to the wishes of the other. Let self-denial be the daily aim and practice of each. Never find fault unless it is perfectly certain that a fault has been committed, and always speak lovingly. Never taunt with a past mistake. Neglect the whole world besides rather than one another. Never allow a request to be repeated. Never make a remark at the expense of each other, it is a meanness. Never part for a day without loving words to think of during absence. Never meet without a loving welcome. Never let the sun go down upon any anger or grievance. Never let any fault you have committed go by until you have frankly confessed it and asked forgiveness. Never forget the happy hours of early love. Never sigh over what might have been, but make the best of what is. Never forget that marriage is ordained of God, and that His blessing alone can make it what it should ever be. Never be contented till you know you are both walking in the narrow way. Never let your hopes stop short of the eternal home.

In judging character, too often we mistake rigidity for morality.

Men often mistake themselves, but they never forget themselves.

Nirvana is interpreted by Western nations as the actual annihilation of human desire or passion; but this is a mistake. Nirvana is nothing else than universal reason.

The happy people are those who are producing something; the bored people are those who are consuming much and producing nothing. Boredom is a certain sign that we are allowing our faculties to rust in idleness. When people are bored, they generally look about for a new pleasure, or take a holiday. There is no greater mistake: what they want is some hard piece of work, some productive drudgery. Doctors are fond of sending their fashionable patients to take a rest cure. In nine cases out of ten a work cure would do them far more good.

So far as man stands for anything, and is productive or originative at all, his entire vital function may be said to have to deal with maybes. Not a victory is gained, not a deed of faithfulness or courage is done, except upon a maybe; not a service, not a sally of generosity, not a scientific exploration or experiment or textbook, that may not be a mistake. It is only by risking our persons from one hour to another that we live at all. And often enough our faith beforehand in an uncertified result is the only thing that makes the result come true.

Madmen... do not appear to me to have lost the faculty of reasoning, but having joined together some ideas very wrongly, they mistake them for truths; and they err as men do that argue right from wrong principles. For, by the violence of their imaginations, having taken their fancies for realities, they make right deductions from them.

The highest perfection of intellectual nature lies in a careful and constant pursuit of true and solid happiness; so the care of ourselves that we mistake not imaginary for real happiness, is the necessary foundation of our liberty.

All men who know not where to look for truth, save in the narrow well of self, will find their own image at the bottom, and mistake it for what they are seeking.

We are not immortal, but our acts are... The question is not why we exist but whether we deserve to exist as supposedly rational beings if we act like conquerors rather than caring beings willing to share the planet with all those who are less powerful, and to act with restraint in respecting the needs of others and all life to come. As a species, we are on trial to see whether rationality was an advance or a tragic mistake.

It is a mistake to base one’s hopes for happiness upon the enforcement of security and equality. In principle, both desires are insatiable... No individual or society is secure in a world of emergent probability and sin... To exercise liberty is to take risks, to embrace uncertainties.

It is undoubtedly true that some people mistake sycophancy for good nature, but it is equally true that man more mistake impertinence for sincerity.

It would be a mistake to found a natural science on ‘what we really think’ ... opinions are interpretations, and often misinterpretations, of sense-experience; and the man of science must appeal from these to sense-experience itself, which furnishes his real data. In ethics no such appeal is possible... the moral convictions of thoughtful and well-educated people are the data of ethics just as sense-perceptions are the data of a natural science.

When a law is proposed in the people’s assembly, what is asked of them is not precisely whether they approve of the proposition or reject it, but whether it is in conforming with the general will which is theirs; each by giving his vote gives his opinion on this question, and the counting of votes yields a declaration of the general will. When, therefore, the opinion contrary to my own prevails, this proves only that I have made a mistake, and that what I believed to be the general will was not so. If my particular opinion had prevailed against the general will, I should have done something other than what I had willed, and then I should not have been free. This presupposes, it is true, that all characteristics of the general will are still to be found in the majority; when these cease to be there, no matter what position men adopt, there is no longer any freedom.

The one and only serious mistake is to be afraid of making mistakes.
