The article will focus on the role of faith in postfoundational epistemology and the extent to which our knowledge constructions are only possible in a context of faith. One inherits a language, a house of being, and this inherited language creates the world in which the various beings-of-one’s-world find their place and have meaning. It is in this inherited world-of-meaning that knowledge is constructed. Epistemology is therefore based on faith, believing in the linguistically socially created world, in the sense of believing in the world created by the silent speaking of language that creates the world-of-meaning in which one finds oneself. One unconsciously accepts this world created by language without taking into consideration the role of faith as one believes this created world to be the ‘real’ world. One takes for granted the world (worldview) into which one is born as the way things are. Life and knowledge are made possible by believing this world-of-meaning: language. In a global world where differing worlds-of-meaning come into contact with each other, faith can be disappointed and can lead to anger and violence. If one acknowledges the role of faith in one’s epistemology, doors can be opened to multidisciplinary and multicultural dialogue as a multi-faith conversation.
