desire a larger measure of this quality than they already possess. 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.

For myself, I have never fancied my mind to be in any respect more perfect
than those of the generality; on the contrary, I have often wished that I
were equal to some others in promptitude of thought, or in clearness and
distinctness of imagination, or in fullness and readiness of memory. And
besides these, I know of no other qualities that contribute to the
perfection of the mind; for as to the reason or sense, inasmuch as it is
that alone which constitutes us men, and distinguishes us from the brutes,
I am disposed to believe that it is to be found complete in each
individual; and on this point to adopt the common opinion of philosophers,
who say that the difference of greater and less holds only among the
accidents, and not among the forms or natures of individuals of the same
species.

I will not hesitate, however, to avow my belief that it has been my
singular good fortune to have very early in life fallen in with certain
