And in this it is not likely that all are mistaken the conviction is rather to be held as testifying that the power of judging aright and of distinguishing truth from error, which is properly what is called good sense or reason, is by nature equal in all men; and that the diversity of our opinions, consequently, does not arise from some being endowed with a larger share of reason than others, but solely from this, that we conduct our thoughts along different ways, and do not fix our attention on the same objects. For to be possessed of a vigorous mind is not enough; the prime requisite is rightly to apply it. The greatest minds, as they are capable of the highest excellences, are open likewise to the greatest aberrations; and those who travel very slowly may yet make far greater progress, provided they keep always to the straight road, than those who, while they run, forsake it.

that we conduct our thoughts along different ways, and do not fix our attention on the same objects.

Wide differences of opinion in matters of religious, political, and social belief must exist if conscience and intellect alike are not to be stunted, if there is to be room for healthy growth.

thanks to the discrepancies between people’s thoughts and their actions, and to the diversity of their wishful impulses.

Good sense is, of all things among men, the most equally distributed; for every one thinks himself so abundantly provided with it, that those even who are the most difficult to satisfy in everything else, do not usually desire a larger measure of this quality than they already possess.

I think it's different kinds of minds, and the recognition that certain mental deficiencies may actually have some selective advantages in terms of activities. We've lost a lot of the barriers that have to do with skin color and with various other characteristics. But there's still not sufficient recognition of mental diversities. And we don't all have to think alike to be communal and to live in a productive and satisfying world.

The majority of men is composed of two classes, for neither of which would this be at all a befitting resolution: in the first place, of those who with more than a due confidence in their own powers, are precipitate in their judgments and want the patience requisite for orderly and circumspect thinking; whence it happens, that if men of this class once take the liberty to doubt of their accustomed opinions, and quit the beaten highway, they will never be able to thread the byway that would lead them by a shorter course, and will lose themselves and continue to wander for life; in the second place, of those who, possessed of sufficient sense or modesty to determine that there are others who excel them in the power of discriminating between truth and error, and by whom they may be instructed, ought rather to content themselves with the opinions of such than trust for more correct to their own reason.

It is not best that we should all think alike; it is difference of opinion that makes horse races.

The mind of man can never be wholly barren. Through our whole lives we are subject to successive impressions; for, either new ideas are continually flowing in, or traces of the old ones are marked deeper. If, therefore, you be not acquiring good principles be assured that you are acquiring bad ones; if you be not forming virtuous habits you are, how insensibly soever to yourselves, forming vicious ones…

That is why I can’t in any way approve of those MEDDLESOME and RESTLESS characters who, without being called by BIRTH or by FORTUNE to the management of public affairs, are yet forever thinking up some new reform! If I thought this present work contained the SLIGHTEST ground for suspecting me of such FOLLY, I would SHRINK from allowing it to be published! My plan has NEVER gone beyond trying to reform my own thoughts and to build on a foundation that is ALL MY OWN. If I’m pleased enough with my work to present you with this sketch of it, it’s not because I would advise anyone to imitate it. Those on whom GOD has bestowed more of his favours than he has on me will PERHAPS have higher aims; but I’m afraid that this project of mine may be too bold for many people! The mere decision to rid myself all the opinions I have hitherto accepted isn’t an example that everyone ought to follow! The world is mostly made up of two types of minds for whom it is QUITE unsuitable. (1) There are those who, believing themselves cleverer than they are, can’t help rushing to judgment and can’t muster the patience to direct all their thoughts in an ORDERLY manner. So that if they ONCE took the liberty of doubting the principles they have accepted and leaving the common path, they would NEVER be able to stay on the straighter path that they ought to take, AND would REMAIN lost ALL their LIVES. (2) And there are those who are reasonable enough, or modest enough, to THINK that they can’t distinguish true from false as well as some other people by whom they can be taught. THESE should be content to follow the opinions of those others rather than to seek better opinions themselves.

True progress is not possible without a variety of opinions, for it is only through the friction of variously constituted intellects and through the stimulating effect they have on one another that social problems are gradually clarified and thus brought within the range of solution.
