M. Jour. Pooh! what repulsive words! This logic does not by any means suit me. Teach me something more enlivening.

Prof. Phil. Will you learn moral philosophy?

M. Jour. Moral philosophy?

Prof. Phil. Yes.

M. Jour. What does it say, this moral philosophy?

Prof. Phil. It treats of happiness, teaches men to moderate their passions, and—

M. Jour. No, none of that. I am devilishly hot-tempered, and, morality or no morality, I like to give full vent to my anger whenever I have a mind to it.

Prof. Phil. Would you like to learn physics?

M. Jour. And what have physics to say for themselves?

Prof. Phil. Physics is that science which explains the principles of natural things and the properties of bodies; which discourses of the nature of the elements, of metals, minerals, stones, plants, and animals; which teaches us the cause of all the meteors, the rainbow, the ignis fatuus, comets, lightning, thunder, thunderbolts, rain, snow, hail, and whirlwinds.
