This is a list of keyterms in the Philosophical Dictionary. These are terms for important ideas or terms with many links to other parts of the Dictionary.
Let's start with basic philosophy:
Philosophy: This gives the definition of the OED, and provides links to
First Assumptions, Natural Logic, Natural Philosophy, Natural Realism, Metaphysics, Minimal metaphysics, and Personalism all of which are pretty fundamental. The last two items are worth reading if you believe yourself to be a commonsensical sort of person. Other important items here are Theory, Representing, Reason, and Wisdom.
Another basic concern is logic:
Logic: This gives a simple definition and provides links to
Basic Logic, Classical Propositional Logic, Extended Propositional Logic, Logic Notation, Logical terms, Natural Deduction, and Set Theory all of which are important if you want to know about reasoning. Personal probability gives a system that explains everyday logical reasoning of all kinds based on probability.
Then there are human persons:
Person: This gives a basic definition and exposition and provides links to
Consciousness, Character, Ego, Hypocrisy, Personality, Role, Self, Suffering. Other important related terms are: Brain, Self-deception, Self-interest. An important aside here - it concerns a different type of experience than is normal - is Mysticism. In any case, it is important to be clear about one's personal probabilities and one's capacities for willing, for these are fundamental to all one's believing and acting.
Then there are a number of important illusions and delusions:
Illusion, Delusion, Self-deception, Collusion. In this context other important terms are: Ignorance, Prejudice, Fanaticism and Madness, More specifically but still general, there are: Ideology, Religion, Wishful thinking and their generators: Priests and Clergy. In roughly the same class are most kinds of Politics, in which context Cant and Hypocrisy are important, as are Propaganda and indeed Advertisement. A very normal product and cause of much illusion and delusion is Totalitarianism, for which also see Us, Them, We.
Then there is society:
Society: This gives a basic logical sort of definition and provides links to
Collusion, Conformism, Groups, Hypocrisy, Ideology, Politics, Power, Religion, Prejudice among other things, and also to Metaphysics and Ethics and Morals. Important here are Cooperation, Ends, Agreements, and Promises, and in general terms Leaders, Followers, Ordinary men, Groupthinking and Roles. There also is a useful listing of commented Politics - introductory texts, and items on Anarchism, Conservatism, Liberalism, Socialism and the State and Government. Also relevant here are Authority and Bureaucracy.
Then there is knowledge:
Knowledge: This gives a basic logical sort of definition and provides links to
Belief, Ignorance, Evidence, Experiment, Fallibilism, Science, Scientific knowledge. Here also enter concerns like Adequacy, Wishful thinking, Meaning, Truth and Theory and Representing. Also relevant here are Propositional Attitude and concerns relating to Probability and Certainty.
I wish you much pleasure and enlightenment!
