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.
