1) Ontology is: The study of the genesis and development of individuals. A belief that the order of things is all important. A philosophy of life that guides and informs every action. A branch of metaphysics that deals with the nature of being. The study of Ont, the Greek god of thought.
2) As an empiricist and sceptical philosopher, David Hume believed: The earth orbits round the sun, rather than the reverse. The sun is a flaming orb, placed in the celestial vault by God to warm his creation. You cannot deduce the rising of the sun tomorrow from its past behaviour. The actions of the sun can be deduced from observation. The sun shone out of his arse.
