{3d03 affectus} NOT afficere

Meaning Sense 1: affectus-corpusaffectio corporis humanis, a corporeal emotion or affection of the human body.
Sense 2: affectus-mens: mental emotion: the idea of an affectus-corpus in the mind. {2p12} claims that the mind never fails to have an idea of an affection of the body - though that idea can be inadequate. An affectus-mens is a new idea, a state change of the mind occuring when the mind perceives an affectus-corpus. That idea, like every modus, is an affectio, NOT directly caused by an external thing (res externa) but indirectly, by the impact (affectio) on the human body caused by the external thing. This complicated process of impact absorption is called imagining. This process, if not accompanied by understanding,  will lead to an imagined idea that is not, in the mind, ordered and concatenated isomorphic to the order (in God = natura-sense 2 = substance) of the body-affection that the mind perceived. Such an idea idea is inadequate (though may, by a stroke of luck, be true).
Subsets (kinds) All kinds of emotions from {3de1} to {3de48} (but note that {3de04 admiratio} in its explanation is denied the status of an emotion.

GENERAL DEFINITION OF THE EMOTIONS. Emotion, which is called a passivity of the soul, is a confused idea, whereby the mind affirms concerning its body, or any part thereof, a force for existence (existendi vis) greater or less than before, and by the presence of which the mind is determined to think of one thing rather than another. AFFECTUUM GENERALIS DEFINITIO. Affectus qui animi pathema dicitur, est confusa idea qua mens majorem vel minorem sui corporis vel alicujus ejus partis existendi vim quam antea affirmat et qua data ipsa mens ad hoc potius quam ad illud cogitandum determinatur.

... the mind's power over the emotions consists:--
I. In the actual knowledge of the emotions (V. iv. note).
II. In the fact that it separates the emotions from the thought of an external cause, which we conceive confusedly (V. ii. and V. iv. note).
III. In the fact, that, in respect to time, the emotions referred to things, which we distinctly understand, surpass those referred to what we conceive in a confused and fragmentary manner (V. vii.).
IV. In the number of causes whereby those modifications [Lat: affectiones][17] are fostered, which have regard to the common properties of things or to God (V. ix. xi.).
V. Lastly, in the order wherein the mind can arrange and associate, one with another, its own emotions (V. x. note and xii. xiii. xiv.) ...
... mentis in affectus potentiam consistere
I. in ipsa affectuum cognitione (vide scholium propositionis 4 hujus 5p04s).
II. in eo quod affectus a cogitatione  causae externae quam confuse imaginamur, separat (vide propositionem 2 {5p02} cum scholio propositionis 4 hujus 5p04s).
III. in tempore quo affectiones quae ad res quas intelligimus referuntur, illas superant quae ad res referuntur quas confuse seu mutilate concipimus (vide propositionem 7 hujus).
IV. in multitudine causarum a quibus affectiones quae ad rerum communes proprietates vel ad Deum referuntur, foventur (vide propositiones 9 {5p09} et 11 {5p11} hujus).
V. denique in ordine quo mens suos affectus ordinare et invicem concatenare potest (vide scholium propositionis 10 5p10s et insuper propositiones 12 {5p12}, 13 {5p13} et 14 {5p14} hujus).
