From Moliere’s Le Bourgeois gentilhomme, translated by A. R. Waller:
Teacher of Philosophy: […] What do you wish to learn?
Monsieur Jourdain: Everything I can, for I am intensely anxious to be learned; it troubles me that my father and my mother did not see that I was thoroughly grounded in all knowledge when I was young.
Teacher of Philosophy: An admirable sentiment: Nam sine doctrina vita est quasi mortis imago. Doubtless you know Latin and understanding that.
Monsieur Jourdain: Yes, but proceed as thought I did not know it: explain to me what it means.
Teacher of Philosophy: It means, Without knowledge, life is little more than the reflection of death.
Monsieur Jourdain: That Latin is right.
Teacher of Philosophy: Do you not know some of the principles, some of the rudiments of knowledge?
Monsieur Jourdain: Oh! Yes, I know how to read and write.
Teacher of Philosophy: Where would you like us to begin? Would you like me to teach you logic?
Monsieur Jourdain: What is logic?
Teacher of Philosophy: It teaches that which educates the three operations of the mind.
Monsieur Jourdain: What are the three operations of the mind?
Teacher of Philosophy: The first, the second and the third. The first is to have a proper conception of things, by means of universals; the second is to judge accurately, by means of categories; and the third is to draw a conclusion accurately by means of the figures Barbara, Celarent, Durii, Ferio, Baralipton, etc.
Monsieur Jourdain: Those words are regular jawbreakers. That logic does not appeal to me. Let us learn something nicer.
