Whether the seven gifts of the Holy Ghost are suitably enumerated?

Objections

Objection 1 : It would seem that seven gifts of the Holy Ghost are unsuitably enumerated. For in that enumeration four are set down corresponding to the intellectual virtues, viz. wisdom, understanding, knowledge, and counsel, which corresponds to prudence; whereas nothing is set down corresponding to art, which is the fifth intellectual virtue. Moreover, something is included corresponding to justice, viz. piety, and something corresponding to fortitude, viz. the gift of fortitude; while there is nothing to correspond to temperance. Therefore the gifts are enumerated insufficiently.
Objection 2 : Further, piety is a part of justice. But no part of fortitude is assigned to correspond thereto, but fortitude itself. Therefore justice itself, and not piety, ought to have been set down.
Objection 3 : Further, the theological virtues, more than any, direct us to God. Since, then, the gifts perfect man according as he is moved by God, it seems that some gifts, corresponding to the theological virtues, should have been included.
Objection 4 : Further, even as God is an object of fear, so is He of love, of hope, and of joy. Now love, hope, and joy are passions condivided with fear. Therefore, as fear is set down as a gift, so ought the other three.
Objection 5 : Further, wisdom is added in order to direct understanding; counsel, to direct fortitude; knowledge, to direct piety. Therefore, some gift should have been added for the purpose of directing fear. Therefore the seven gifts of the Holy Ghost are unsuitably enumerated.
