Why the "intensio"

I guess "intensio" was the metaphysical category I wanted to put "passio" in - "passio" in the active sense, or rather to highlight one dimension of "passio" because that obviously does not constitute the main notio of passio according to Aquinas which he gives himself. And that is one thing that I have to remember - although he himself brings in that word.

[34529] Iª-IIae q. 22 a. 2 ad 1 Ad primum ergo dicendum quod e contrario se habet in his quae pertinent ad perfectionem, et in his quae pertinent ad defectum. Nam in his quae ad perfectionem pertinent, attenditur intensio per accessum ad unum primum principium, cui quanto est aliquid propinquius, tanto est magis intensum lucidi attenditur per accessum ad aliquid summe lucidum, cui quanto aliquid magis appropinquat, tanto est magis lucidum.
Sed in his quae ad defectum pertinent, attenditur intensio non per accessum ad aliquod summum, sed per recessum a perfecto, quia in hoc ratio privationis et defectus consistit. Et ideo quanto minus recedit a primo, tanto est minus intensum, et propter hoc, in principio semper invenitur parvus defectus, qui postea procedendo magis multiplicatur. Passio autem ad defectum pertinet, quia est alicuius secundum quod est in potentia. Unde in his quae appropinquant primo perfecto, scilicet Deo, invenitur parum de ratione potentiae et passionis, in aliis autem consequenter, plus. Et sic etiam in priori vi animae, scilicet apprehensiva, invenitur minus de ratione passionis.

"In things pertaining to defect, the tendency is stretched not to access to height of something, but through regression from perfection, because this is what the notion of privation and defect consist. And therefore so far as something recedes little from the first, so is it less intense, and because of this, in the beginning, therei s always found a little defect, which as it progresses is more multiplied. Now passion pertains to defect, because it is of something that is in potency. Whence in those things which draw near to the prime perfection, namely God, little is found of the ratio of potency and passion, in those things which follow, more. And so in the prior powers of the soul, that is the apprehensive, there is found less of the ratio of passion."

I just found the Oxfod dictionary here in the library. And here's what they give for "intensio". First, they put it under 'intentio". And this is what they say: 1) the action of stretching, extension, spasm. b) a state of physical tension, tautness. 2) concentrated attention (of the eyes) gaze. b) the forcing or straining (of the voice). 3.) The state of being intense or severe, intensity, intensification. 4) Mental effort, attention, concentration. 5) aim, purpose, intention. (6 a logical function not related to my point).
I'm going to ask someone who knows...
