per se (not comparable)

1. (philosophy) Positing itself and being a principle of its own determination.
   • 1988, J. van Rijen, Aspects of Aristotle’s Logic of Modalities, page 137:

     Before stating at 74b5ff. that the connection between the subject and predicate of the premisses of scientific inferences must not be accidental but per se, he introduces the technical terms 'about all' ( 'kata pantos' ) and 'per se' (' kath' hauto ') in order to clarify the meaning of this proviso.

     The per se cause of the house is the building skill and the craftsman who exercises it, while the per accidens cause is the fair-skinned or the artistic man. Alexander says: 'Aristotle says that just as anything that exists is one thing per se and another per accidens (by “being what it is per se” he means the substance, and by "what is per accidens" he means the attributes of the substance), so a cause is one thing per se and another per accidens.

   • 2015, Gaven Kerr, Aquinas's Way to God: The Proof in De Ente et Essentia:

     They hold to the impossibility of an actual per se infinity, because in a per se series the effects have a dependence on their causes, in which case if the series were infinite, the ultimate effect would be dependent on an infinite chain of causes; and since an infinity cannot be traversed, the being of such an effect would never be explained.
