Understanding Inference and Vyapti in Logic

Inference, known as Anumana in Sanskrit, is the process of deriving knowledge based on existing information or observations. It can be used for personal understanding or to demonstrate truths to others. An inference may be SvArtha (for oneself) or ParArtha (for others). Vyapti, the invariable concom
