Topicality (philosophy)

from Wikipedia, the free encyclopedia

In philosophy , topicality is spoken of in different contexts with correspondingly different meanings , including

  • In ontology : actuality refers to Aristotle's talk of act and potency or of ontological dispositions .
    • In a more specific sense, God and his being or his knowledge can be spoken of as a pure act actus purus (without unfulfilled potentiality).
    • Furthermore, a distinction is made now and then between potential and actual infinity ( realists with regard to mathematical entities would, for example, be obliged to an actual infinity if, for example, the class or series of natural numbers is infinite; such ontological obligations to actual infinities, on the other hand, are excluded from the outset by other theorists)
  • In logic , more precisely in modal logic : Actuality here means that which is not only logically possible or even logically impossible, but (contingently or necessarily) actually the case, according to some conceptions about modality : that which is possible in a certain one among many Worlds is the case, namely that world in which we (which we use or evaluate a language expression) actually live in.
