Ascent of Mount Carmel

Which treats of the purgation of the active night of the memory and will. Gives instruction how the soul is to behave with respect to the apprehensions of these two faculties, that it may come to union with God, according to the two faculties aforementioned, in perfect hope and charity.

The first faculty of the soul, which is the understanding, has now been instructed, through all its apprehensions, in the first theological virtue, which is faith, to the end that, according to this faculty, the soul may be united with God by means of the purity of faith. It now remains to do likewise with respect to the other two faculties of the soul, which are memory and will, and to purify them likewise with respect to their apprehensions, to the end that, according to these two faculties also, the soul may come to union with God in perfect hope and charity. This will briefly be effected in this third book. We have now concluded our treatment of the understanding, which is the receptacle of all other objects according to its mode of operation; and in treating of this we have gone a great part of the whole way. It is therefore unnecessary for us to write at equal length with respect to these faculties; for it is not possible that, if the spiritual man instructs his understanding in faith according to the doctrine which has been given him, he should not, in so doing, instruct the other two faculties in the other two virtues likewise; for the operations of each faculty depend upon the others.

2. But since, in order to follow our manner of procedure, and in order, too, that we may be the better understood, we must necessarily speak of the proper and determinate matter, we shall here be obliged to set down the apprehensions proper to each faculty, and first, those of the memory, making here such distinction between them as suffices for our purpose. This we shall be able to deduce from the distinction between their objects, which are three: natural, imaginary and spiritual; according to which there are likewise three kinds of knowledge which come from the memory, namely: natural and supernatural,⁴⁸⁰ imaginary and spiritual.

3. All these, by the Divine favour, we shall treat here in due course, beginning with natural knowledge, which pertains to the most exterior objects. And we shall then treat of the affections of the will, wherewith we shall conclude this third book of the active spiritual night.

480. It will be seen from what follows that in practice the Saint preserves the strictly tripartite division given in the text above, supernatural knowledge being found in each of the sections.
