How often, and, peradventure, how foolishly, have I extended my book to
make it speak of itself; foolishly, if for no other reason but this, that
it should remind me of what I say of others who do the same: that the
frequent amorous glances they cast upon their work witness that their
hearts pant with self-love, and that even the disdainful severity
wherewith they scourge them are but the dandlings and caressings of
maternal love; as Aristotle, whose valuing and undervaluing himself often
spring from the same air of arrogance. My own excuse is, that I ought in
this to have more liberty than others, forasmuch as I write specifically
of myself and of my writings, as I do of my other actions; that my theme
turns upon itself; but I know not whether others will accept this excuse.

I observed in Germany that Luther has left as many divisions and disputes
about the doubt of his opinions, and more, than he himself raised upon
the Holy Scriptures. Our contest is verbal: I ask what nature is, what
pleasure, circle, and substitution are? the question is about words, and
is answered accordingly. A stone is a body; but if a man should further
urge: "And what is a body?"--"Substance"; "And what is substance?" and
so on, he would drive the respondent to the end of his Calepin.

[Calepin (Ambrogio da Calepio), a famous lexicographer of the
fifteenth century. His Polyglot Dictionary became so famous, that
Calepin became a common appellation for a lexicon]

We exchange one word for another, and often for one less understood.
I better know what man is than I know what Animal is, or Mortal, or
Rational. To satisfy one doubt, they give me three; 'tis the Hydra's
head. Socrates asked Menon, "What virtue was." "There is," says Menon,
"the virtue of a man and of a woman, of a magistrate and of a private
person, of an old man and of a child." "Very fine," cried Socrates,
"we were in quest of one virtue, and thou hast brought us a whole
swarm." We put one question, and they return us a whole hive. As no
event, no face, entirely resembles another, so do they not entirely
differ: an ingenious mixture of nature. If our faces were not alike, we
could not distinguish man from beast; if they were not unlike, we could
not distinguish one man from another; all things hold by some similitude;
every example halts, and the relation which is drawn from experience is
always faulty and imperfect. Comparisons ar
