Whether wisdom is merely speculative, or practical also?

Objection 1: It would seem that wisdom is not practical but merely speculative. For the gift of wisdom is more excellent than the wisdom which is an intellectual virtue. But wisdom, as an intellectual virtue, is merely speculative. Much more therefore is wisdom, as a gift, speculative and not practical.

Objection 2: Further, the practical intellect is about matters of operation which are contingent. But wisdom is about Divine things which are eternal and necessary. Therefore wisdom cannot be practical.

Objection 3: Further, Gregory says (Moral. vi, 37) that "in contemplation we seek the Beginning which is God, but in action we labor under a mighty bundle of wants." Now wisdom regards the vision of Divine things, in which there is no toiling under a load, since according to Wis. 8:16, "her conversation hath no bitterness, nor her company any tediousness." Therefore wisdom is merely contemplative, and not practical or active.

On the contrary, It is written (Col. 4:5): "Walk with wisdom towards them that are without." Now this pertains to action. Therefore wisdom is not merely speculative, but also practical.

I answer that, As Augustine says (De Trin. xii, 14), the higher part of the reason is the province of wisdom, while the lower part is the domain of knowledge. Now the higher reason according to the same authority (De Trin. xii, 7) "is intent on the consideration and consultation of the heavenly," i.e. Divine, "types" [*Cf. FP, Question [79], Article [9]; FS, Question [74], Article [7]]; it considers them, in so far as it contemplates Divine things in themselves, and it consults them, in so far as it judges of human acts by Divine things, and directs human acts according to Divine rules.

Accordingly wisdom as a gift, is not merely speculative but also practical.

Reply to Objection 1: The higher a virtue is, the greater the number of things to which it extends, as stated in De Causis, prop. x, xvii. Wherefore from the very fact that wisdom as a gift is more excellent than wisdom as an intellectual virtue, since it attains to God more intimately by a kind of union of the soul with Him, it is able to direct us not only in contemplation but also in action.

Reply to Objection 2: Divine things are indeed necessary and eternal in themselves, yet they are the rules of the contingent things which are the subject-matter of human actions.

Reply to Objection 3: A thing is considered in itself before being compared with something else. Wherefore to wisdom belongs first of all contemplation which is the vision of the Beginning, and afterwards the direction of human acts according to the Divine rules. Nor from the direction of wisdom does there result any bitterness or toil in human acts; on the contrary the result of wisdom is to make the bitter sweet, and labor a rest.
