Kairos is an educational charity specifically founded by Keith Critchlow to promote the recovery of traditional (perennial) values in the Arts and Sciences. This is based on the Unity of Being and the fundamental inter-relatedness of all things. For the ancient Greeks, the word 'mathema' originally meant 'study', so the four mathematical Arts/Sciences we know as the Quadrivium can be understood as uniting the nature of inner perception by which we 'study' and the nature of the source of our impressions of the outer world. Integrity being the first principle.
