Abstract

Otto Duintjer is one of the philosophers who have anew put the theme of spirituality on the philosophical agenda. Indeed, philosophy understood as striving for wisdom has had a spiritual dimension from the outset. But in modern time that dimension has eclipsed ever more, especially in academic philosophy. An important reason is that philosophy has adapted itself to a model of science, for which a 'disinterested' and 'neutral' attitude of the knowing subject and a hypothetical form of thinking are charasteristic. In the logic of this type of science, and hence of a corresponding philosophy, existential and metaphysical questions and the theme of transcendence, which are essential for spirituality, fundamentally have no place. An important line of modern thinking, of which Kant and Wittgenstein are leading representatives and that Duintjer also takes as his starting-point, acknowledges the significance of these questions. But it also thinks that they can only be handled in a negative and indirect way. At the basis of that is an epistemological conception that understands knowledge exclusively as fully explicit knowledge. But if knowledge can also comprise all sorts of partially explicated or 'tacit' knowledge, as twentieth century philosophy has come to think, perspectives are opened for forms of spiritual knowledge that are not solely dependent on negative or indirect ways of reaching them
