Occam's dictum "Entia non multiplicanda sunt praeter necessitatem" was inspired by a spirit similar to that of Bacon.
On the whole, there is no reason to doubt Occam's honest adhesion to each of the two guides whose contrariety he laboured to display.
The principle of the twofold nature of truth 1 thus embodied in Occam's system was unquestionably adopted by many merely to cloak their theological unbelief; and it is significant of the internal dissolution of Scholasticism.
In 1339 Occam's treatises were put under a ban by the university of Paris, and in the following year Nominalism was solemnly condemned.
The title " last of the Scholastics " is commonly given to Gabriel Biel, the summarizer of Occam's doctrine.
Here he studied scholastic philosophy and theology under a pupil of Occam's, from whom he imbibed the nominalist conception of philosophy; in addition he studied canon law, medicine, astronomy and even magic, and apparently some Hebrew.
It was for Occam's share in this controversy that he was best known in his lifetime.
The fundamental principles of his system (see Scholasticism) are that "Essentia non sunt multiplicanda praeter necessitatem" ("Occam's Razor"), that nouns, like algebraical symbols, are merely denotative terms whose meaning is conventionally agreed upon (suppositio), and that the destructive effect of these principles in theological matters does not in any way destroy faith (see the Centilogium Theologicum, Lyons, 1495, and Tractatus de Sacramento Altaris).
After Occam's days the opinions of Francis prevailed in many quarters, but the genuine Franciscans had no place within the church.
