pp1d01 se^alius

Forms se^alius, suus^alterius, in se^in alio, intra^extra, ipso^aliud, internus^externus, intrinsecus^extrinsecus, immanens^transiens
Meaning About things (res) and their environment. A thing itself versus other things. Within^outside something (res).  Terms to express what is the thing itself, what is in the thing, and what other things there are outside the thing. These complement pairs of in/out concepts serve to discriminate between things (res) of which the operation or effect is caused by passion (from outside) or by their own action (from within).
Only God = natura-sense 2 = substance is causa sui (of itself). Other things (res), by defnition all in God, can at most be adequate / partial / accidental cause of other things and in their turn can have other things as adequate / partial / accidental cause and so on, until infinity (in suo genere).
In se^in alio when about ideas: ideas are things-sense-1: res-modus:
A
The truth (veritas) of an adequate idea is caused by the idea itself (internally) and is certain.
B An inadequate idea can (by a stroke of luck during its imagination) be true (vera), but this is caused externally and never certain.
C The falsity of a false idea is always caused externally, there's never anything wrong with an idea in itself (more: veritas).
"Per se concipere/considerare": conceiving/considering something by thinking of it without invoking any other (per aliud)) thought or idea (instead of per aliud, per accidens also is used as a logical opposition)
