Key terms in philosophy

  1. Axiology is the study of the good. Where do moral rules come from? What is the good life? Are there moral truths?
  2. Epistemology is the study of knowledge. What is knowledge? How does it differ from belief? What is the nature of evidence? What is truth? Certainty?
  3. Metaphysics is the study of reality. Dualism? Monism? What is real? Universals or particulars?
  4. Ontology is the study of being. If we take an inventory of the universe what do we find? Matter/mind?
  5. Logic is the study of argument. Deductive/inductive. Valid/invalid. Strong/weak.

For Plato:

  1. axiology: the Good is knowable and fixed; i.e., ethics can be taught; rules of conduct exist independent of time and place
  2. epistemology: knowledge without experience is possible
  3. metaphysics: universals are real; particulars are trivial
  4. ontology: the real is transcendent and accessible only through reason; dualism describes the world
  5. Reductio ad absurdum is a mode of argumentation that seeks to establish a contention by deriving an absurdity from its denial, thus arguing that a thesis must be accepted because its rejection would be untenable. It is a style of reasoning that has been employed throughout the history of mathematics and philosophy from classical antiquity onwards.

Limits of reason

Reason as a way of knowing has always been at the heart of philosophical discussion. The current and recent centuries are no different.

  • It is difficult if not impossible to separate “reason” from the history of philosophy for an analysis, per simpliciter, for every philosopher has some take on reason since it is the heart of the philosophical enterprise.
  • Historically the conversation has been one of the pre-eminence of reason as a faculty for knowing. In that respect the initial conflict in modern philosophy was between revelation and reason. Descartes tried to bridge that gap by arguing that one could reason one’s way to one’s own existence and then to the necessary existence of God. He then attempted to build an epistemology on that foundation.
  • For Descartes it is the will that causes us to make errors and not a faulty faculty of reason.
  • The empiricists found flaws in Cartesian epistemology arguing that there were no innate ideas at all and that we humans are blank slates written upon by experience.
  • Kant tried valiantly to put the humpty dumpty together again by bringing empiricism and rationalism together in his synthetic-aprioris.
  • Psychology, as it broke away from philosophy, proposed behaviourism as the theory, a variation on some stimulus, response, reward (SRR) description.
  • Linguistics, in the person of Noam Chomsky, argued (see his Cartesian Grammar) that we know more than we should if behaviourism is true. The famous debates between Chomsky and Skinner are central to understanding these ideas.
  •  Russell’s work in logic and mathematics shows us that knowing how is more important than knowing that, since all logical systems including complex mathematical systems are based upon tautologies.
  • Cognitive Science departments are established with faculty from psychology, philosophy, and computer science to investigate the exciting idea of artificial intelligence. Most of the AI work is heavily Cartesian, with transcendental “minds” housed in machines as well as in bodies.
  • Biology takes the forefront with fascinating science showing that brains are minds and that reason is a “faculty” to be found not only in male philosophers, but also in females and in other “lower” species.
  • Reason, it seems, has a benefit for survival of our species. It is far superior to magic, religious mumbo-jumbo, pot smoking, channeling, ESP, crystal gazing, Freudian repressed urges, authority of church or state, and the like at presenting us with testable information about the world and ourselves. It allows us to search for causal relations even though we cannot prove that the proposition “Every event has a cause” is true.
