And in return, their host to pay, left each a book behind.”

[35] Hence probably the origin of the proverb, “Amicus Plato, sed magis amica veritas”—“Plato is dear, but truth is dearer.”

[36] The difference between reasoning by Deduction and by Induction may be made clearer by the following examples:—

Deduction.—Dogs are quadrupeds.

Tray is a dog.

Therefore, Tray is a quadruped.

Induction.—Tray is a quadruped; Carlo is a quadruped; Fan is a quadruped;

Pet is a quadruped; etc.

Tray, Carlo, Fan, Pet, etc., are dogs.

Therefore, all dogs are quadrupeds.
