Whether happiness consists in the consideration of speculative sciences?

❌ Objection 1 : It would seem that man's happiness consists in the consideration of speculative sciences. For the Philosopher says (Ethic. i, 13) that "happiness is an operation according to perfect virtue." And in distinguishing the virtues, he gives no more than three speculative virtues---"knowledge," "wisdom" and "understanding," which all belong to the consideration of speculative sciences. Therefore man's final happiness consists in the consideration of speculative sciences.

❌ Objection 2 : Further, that which all desire for its own sake, seems to be man's final happiness. Now such is the consideration of speculative sciences; because, as stated in Metaph. i, 1, "all men naturally desire to know"; and, a little farther on (2), it is stated that speculative sciences are sought for their own sakes. Therefore happiness consists in the consideration of speculative sciences.

❌ Objection 3 : Further, happiness is man's final perfection. Now everything is perfected, according as it is reduced from potentiality to act. But the human intellect is reduced to act by the consideration of speculative sciences. Therefore it seems that in the consideration of these sciences, man's final happiness consists.
