In the Topics, Aristotle   defines συλλογισμóς as a “λóγος [an ἀποφαίνεσθαι, a kind of speaking “letting-see”] in which something else comes about, results in addition [something else results in the sense of speaking, is seen, exhibited], something other than that which lies before us from the outset [something other than that which is presupposed as known, from which one proceeds in exhibiting.]” In this συλλογίζεσθαι, something is introduced, something other than that from which it proceeds, becomes visible. Something else becomes visible precisely “by way of that from which it proceeds.” [Heidegger  , GA18:129]
