Doxa : from the Greek, opinion, way of thinking. According to Parmenides, the world of doxa was the world of the opinions of mortals. When substituted by “what is” for what seems to be, or when mortals concur to manipulate things, or understand themselves, it becomes a falsehood or an error. Husserl held that all expressions are a doxic act in their full sense, i.e, a certainty, a belief. 1
