The article discusses the causes for the formation of the polysemanticity of the Latin word virtus (virtue; strength, valor, masculinity) and term virtual , which was derived from virtus . The emergence of the polysemantic character of virtual became possible due to the unique semantics of the word virtus , in which there are two dominant meanings – virtue and strength . According to Ekaterina Taratuta, there are two lines of constructing the meanings of concepts based on the root vir(t) – “Platonic” and “Aristotelian.” We believe that on the basis of the first semantic “dominant” of the word virtus (virtue) a “Platonic” group of meanings of the word virtual was formed, and on the basis of the second “dominant” (strength) the “Aristotelian” group of meanings was formed. The first cause of the existence of the “Platonic” group of the meanings of virtual is the translation of the Greek word ἀρετή using the Latin word virtus in Roman philosophy, Biblical texts and Greek-Byzantine patristic writings, as a result of which the concept of virtus has been enriched with the meanings of the Platonic and Christian concept of ἀρετή . The second cause is that through the Plato’s doctrine of arete-eidos the concept of virtus has been enriched with the meanings of the Platonic concept of εἶδος . As Hans Kremer has shown, in Plato’s doctrine eidos is the source of order and beauty, which is reflected in the empirical world as arete – virtue, goodness; thus, eidos is inextricably linked with arete . As a result, in the “Platonic” sense the virtual is understood as the eidetic , the ideal . The first cause of the existence of the “Aristotelian” group of meanings of virtual is the translation of the Greek word δύναμις using the Latin word virtus in Biblical texts and in Greek-Byzantine patristic writings, as a result of which the concept of virtus has been enriched with the Christian meanings of concept of δύναμις . The second cause is the translation of the Aristotelian concept of δύναμις using the Latin word potentia : the word δύναμις has become the medium, linking the words virtus and potentia and, under the influence of the latter, differences in the meanings of virtus and potentia (and especially their derivatives virtualis (virtual) and potentialis (potential)) have gradually disappeared. As a result, in the “Aristotelian” sense the virtual is understood as the potential, the possible .
