Prexis

The active, deliberate control and examination of assent (synkatathesis) to impressions at the moment they arise.

Prexis is the practical enactment of Prosoche (self-attention) as conscious action. It denotes the active moment in which the mind interrupts an incoming impression (phantasia) and examines it before granting assent. Prexis is not passive observation but vigorous intervention — the capacity to cross-examine the witness in court rather than believing them blindly. It forms the practical bridge between the involuntary impression and the conscious act of assent.
