prejudices kept pace with my classical ones; and there was a time when I
thought it impossible for the honestest man in the world to be saved out
of the pale of the Church of England, not considering that matters of
opinion do not depend upon the will; and that it is as natural, and as
allowable, that another man should differ in opinion from me, as that I
should differ from him; and that if we are both sincere, we are both
blameless; and should consequently have mutual indulgence for each other.

The next prejudices that I adopted were those of the 'beau monde', in
which as I was determined to shine, I took what are commonly called the
genteel vices to be necessary. I had heard them reckoned so, and without
further inquiry I believed it, or at least should have been ashamed to
have denied it, for fear of exposing myself to the ridicule of those whom
I considered as the models of fine gentlemen. But I am now neither
ashamed nor afraid to assert that those genteel vices, as they are
falsely called, are only so many blemishes in the character of even a man
of the world and what is called a fine gentleman, and degrade him in the
opinions of those very people, to whom he, hopes to recommend himself by
them. Nay, this prejudice often extends so far, that I have known people
pretend to vices they had not, instead of carefully concealing those they
had.

always prove an unerring guide; for human reason is not infallible; but
it will prove the least erring guide that you can follow. Books and
conversation may assist it; but adopt neither blindly and implicitly; try
