Heidegger
Heidegger discusses facticity as the thrownness (Geworfenheit) of individual existence, which is to say we are "thrown into the world." By this, he is not only referring to a brute fact, or the factuality of a concrete historical situation, e.g., "born in the '80s." Facticity is something that already informs and has been taken up in existence, even if it is unnoticed or left unattended. As such, facticity is not something we come across and directly behold. In moods, for example, facticity has an enigmatic appearance, which involves both turning toward and away from it. For Heidegger, moods are conditions of thinking and willing to which they must in some way respond. The thrownness of human existence (or Dasein) is accordingly disclosed through moods.
