regard to Truth
If any part of Morals had the simplicity of an instinct, it would be
regard to Truth. The difference between truth and falsehood might
almost be regarded as a primitive susceptibility, like the difference
between light and dark, between resistance and non-resistance. That
each person should say what is, instead of what is not, may well seem
a primitive and natural impulse. In circumstances of perfect
indifference, this would be the obvious and usual course of conduct;
being, like the straight line, the shortest distance between two
points. Let a motive arise, however, in favour of the lie, and there
is nothing to insure the truth. Reference must be made to other parts
of the mind, from which counter-motives may be furnished; and the
intuition in favour of Truth, not being able to support itself, has to
repose on the general foundation of all virtue, the instituted
recognition of the claims of others.
