With the former, mathematical things share the permanence and consistency of their properties; with the latter, they share divisibility and the possibility of being multiplied. Hence, a geometrical figure exists simultaneously on four different levels: as a noetic concept in the intellect; as a logical definition, or logos, in discursive reasoning; as an imaginary perfect figure in the imagination; and as a physical imitation or representation in sense-perception. Imagination, then, can be equated with the intelligible or geometrical matter that constitutes the medium in which a geometrical object can be constructed, represented, and studied.","PeriodicalId":118183,"journal":{"name":"Neoplatonism in Late Antiquity","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124463191","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Proclus then demonstrates that in mathematical objects beauty transpires in four ways: in the beautiful shape of a sensible reproduction of a geometrical figure; in the beauty of the perfect geometrical figure existing in the intelligible matter of the imagination; in the mathematical object’s definition, with all its properties becoming explicit in constructions and demonstrations by discursive reasoning; and in the beauty of the form in the intellect.

Proclus also aims to develop a universal theory of motion or physical change that establishes the first principles as definitions, formulates and demonstrates a number of mutually related propositions about natural objects, and culminates in establishing the existence and properties of the prime mover.

Yet, on the other hand, it also establishes the soul as both uniting and separating, and hence as mediating between the intelligible and the sensible. In his psychology, Plotinus provides explanations for the unity of the soul and for its individuation, which he understands from the perspective of the synthetic unity of the one and the many.

In Ennead I.8, Plotinus presents matter as utter deficiency, as the absence, lack, or privation of the good, and thus as radical evil. In De malorum subsistentia, Proclus explicitly responds to Plotinus and argues that evil does not exist since non-being does not exist. This means that evil is not opposite to the good because the good has no opposite, and opposites belong to the same genus. Therefore, in its elusive and indefinite nature, evil should be characterized by the rethought and redefined concepts of privation, subcontrariety, and parypostasis. In its inescapable deficiency, then, evil is the privation and subcontrary of the good that exists parypostatically; that is, as elusively present in its absence as the misplacement of being and the displacement of the good.","PeriodicalId":118183,"journal":{"name":"Neoplatonism in Late Antiquity","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116864665","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This chapter argues, first, that the notion of intelligible matter plays an important role not only in Plotinus’ earlier treatises but also throughout the entire corpus of his works; second, that bodily matter and intelligible matter are necessarily related as different yet inseparable; and third, that intelligible matter is not only represented by the indefinite dyad and constitutes the primary indefiniteness of the thinking of the intellect, but is also connected with the imagination and thus with geometrical objects.","PeriodicalId":118183,"journal":{"name":"Neoplatonism in Late Antiquity","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115294623","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This requires a careful reading of the relevant texts in Plato and Aristotle and also a meticulous reconstruction of the arguments in the Enneads. Memory for Plotinus is not the Platonic storage of images or imprints coming from the sensible or the intelligible. Rather, memory is a power of imagination used by the soul for the reconstruction and reproduction of the currently absent, which the soul performs starting with the initial sensible impact that becomes the occasion to form a particular memory. Recollection, on the contrary, takes the form of a rational discursive rethinking that reproduces the soul’s experience of the intelligible objects.
