Our understanding are always liable to error. Nature and certainty is very hard to come at; and infallibility is mere vanity and pretense.
A small error in the beginning is a great one in the end.
People first abandon reason, and then become obstinate; and the deeper they are in error the more angry they are.
The trouble of the many and various aims of mortal men bring them much care, and herein they go forward by different paths but strive to reach one end, which is happiness. And that good is that, to which if any man attain, he can desire nothing further... Happiness is a state which is made perfect by the union of all good things. This end all men seek to reach, as I said, though by different paths. For there is implanted by nature in the minds of men a desire for the true good; but error leads them astray towards false goods by wrong paths.
The confirmed prejudices of a thoughtful life are as hard to change as the confirmed habits of an indolent life; and as some must trifle away age because they trifled away youth, others must labor on in a maze of error because they have wandered there too long to find their way out.
Every error is truth abused.
Error is discipline through which we advance.
Mistake, error, is the discipline through which we advance.
The more discussion the better, if passion and personality be eschewed; and discussion, even if stormy, often winnows truth from error - a good never to be expected in an uninquiring age.
Thought precedes the will to think, and error lives ere reason can be born. Reason, the power to guess at right and wrong, the twinkling lamp of wand'ring life, that winks and wakes by turns fooling the follower 'twixt shade and shining.
With endless patience you shall carry out your duty, and your firmness shall be tempered with tenderness for your people. Neither anger nor fury shall lodge in your mind, and all your words and actions shall be marked with calm deliberation. In all your deliberations in the Council, in your efforts at lawmaking, in all your official acts, self-interest shall be cast into oblivion. Cast not away the warnings of any others, if they should chide you for any error or wrong you may do, but return to the way of the Great Law, which is just and right. Look and listen for the welfare of the whole people and have always in view not only the present but also the coming generations, even those whose faces are yet beneath the surface of the earth - the unborn of the future Nation.
Wine is like anger; for it make us strong; blind and impatient; and leads us wrong; the strength is quickly lost; we feel the error long.
Some of the best lessons we ever learn we learn from our mistakes and failures. The error of the past is the wisdom and success of the future.
What we give out as scientific truth is only the product of our own needs and desires, as they are formulated under varying external conditions; that is to say, it is illusion once more. Ultimately we find only what we need to find, and see only what we desire to see. We can do nothing else. And since the criterion of truth, correspondence with an external world, disappears, it is absolutely immaterial what views we accept. All of them are equally true and false. And no one has a right to accuse any one else of error.
All men are good when free from passion, interest, or error.
We frequently fall into error and folly, not because the true principles of action are not known, but because for a time they are not remembered; he may, therefore, justly be numbered among the benefactors of mankind who contracts the great rules of life into short sentences that may early be impressed on the memory, and taught by frequent recollection to occur habitually to the mind.
Wealth is nothing in itself, it is not useful but when it departs from us; its value is found only in that which it can purchase, which, if we suppose it put to its best use by those that posses it, seems not much to deserve the desire or envy of a wise man. It is certain that, with regard to corporal enjoyment, money can neither open new avenues to pleasure, nor block up the passages to anguish. Disease and infirmity still continue to torture and enfeeble, perhaps exasperated by luxury, or promoted by softness. With respect to the mind, it has rarely been observed, that wealth contributes much to quicken the discernment, enlarge the capacity, or elevate the imagination; but may, by hiring flattery, or laying diligence asleep, confirm error, and harden stupidity.
Knowledge rests not upon truth alone, but upon error also.
Vanity indeed is a venial error; for it usually carries its own punishment with it.
Every error of the mind is the more conspicuous and culpable in proportion to the rank of the person who commits it.
