doubtless know Latin?

MONSIEUR JOURDAIN: Yes, but act as if I did not know it. Tell me
what it says.

PHILOSOPHY MASTER: It says that without science life is almost an
image of death.

MONSIEUR JOURDAIN: That Latin is right.

PHILOSOPHY MASTER: Don't you know some principles, some basics of
the sciences?

MONSIEUR JOURDAIN: Oh yes! I can read and write.

PHILOSOPHY MASTER: Where would it please you for us to begin? Would
you like me to teach you logic?

MONSIEUR JOURDAIN: What is this logic?

PHILOSOPHY MASTER: It is that which teaches the three operations of
the mind.

MONSIEUR JOURDAIN: What are these three operations of the mind?

PHILOSOPHY MASTER: The first, the second, and the third. The first
is to conceive well by means of the universals; the second is to
judge well by means of the categories; and the third is to draw
well a conclusion by means of figures. Barbara, Celarent, Darii,
