GLOSSARY
a posteriori A Latin term which means âfrom what is after.â Philosophers use it to refer to knowledge that comes after perceptual experience or depends upon experience for its justification.
a priori A Latin term which means âfrom what is before.â Philosophers use it to refer to knowledge that comes before experience (so-called innate knowledge) or, less controversially, knowledge that does not depend on experience for its justification.
atom Derived from the Ancient Greek word atomos, meaning ânot cuttable.â The Atomists held that everything in the Universe was made up of tiny, indivisible building blocks, moving about in the void, and colliding and combining to form visible objects.
Epicurean Having to do with the philosophy of Epicurus, an ancient Greek Atomist, Hedonist, and perhaps the earliest Empiricist. Sometimes the word points only to a misunderstanding of Epicurusâ hedonistic, moral theory, and means, roughly, âa person devoted to base, bodily pleasures.â
external world The world of objects as they exist apart from our experience of them, as opposed to our inner world of thoughts, perceptions, feelings, and the like.
forms Perfect, unchanging, paradigmatic concept-objects, or archetypes, of the many types of things we see all around us, as posited by Plato. There are, for example, many beautiful thingsâbeautiful paintings, people, landscapes, musical scores, etc.âand what they all have in common is that they resemble the Form, Beautiful. Contemplating the Beautiful, getting to know it, makes one a better judge of beautiful things. The Forms enabled Plato to find a bit of permanence out there, which he thought was necessary for the existence of genuine knowledge.
good Possibly the ultimate Form, according to Plato. According to many commentators, Plato thought that one could only have wisdomâone could really know the other Formsâonly after one grasped the Form of the Good.
ideas A component notion of George Berkeleyâs idealism. Ideas are the passive objects of human knowledge, which can exist only in the mind that perceives them.
indirect awareness Our precarious perceptual connection to the world. If we are directly aware of inner, mental representations of objects in the external world, then we are only indirectly aware of the external world.
material substratum A something, we know not what, supposedly underpinning our perceptions of physical objects. Itâs nothing but a philosopherâs fiction, according to George Berkeley.
mind A component notion of George Berkeleyâs idealism. The mind is a container of ideas or, rather, a thing that knows them, and acts upon them.
purpose A fundamental feature of almost any explanation, for Aristotle. While modern science attempts to understand things by viewing them as purposeless, Aristotle saw purposes, goals, and ends everywhere: smoke rises because it âaims for the heavens,â acorns grow because their end is an oak tree, and so on.
Sun The representation of the Form of the Good in Platoâs cave allegory. Once outside the cave, one is able to see real objects, not just shadows. Just as we are able to see the objects in the world because of the light of the Sun, so, too, Plato suggests, can we understand the Forms once we apprehend the Good itself.
SOCRATESâ METHOD
the 30-second philosophy
Socrates was said to be the wisest man in Athens because he knew that he knew nothing. In the dialogues of Plato, Socrates attempted to spread such wisdom by going around asking people what they thought about a subject, and then asking them tricky questions until they contradicted themselves. For instance, in the dialogue Republic, he asks what âjusticeâ is, and Cephalus suggests it is telling the truth and paying your debts. So, Socrates asks, if you borrow a sword from someone, you owe it to them to give it back, right? But then, what if you know that the person who wants their sword back has gone raving mad? âThere have to be exceptions,â admits Cephalus. So, then, in this case justice requires not giving someone what they are due. Cephalus has undermined his own argument, revealing he doesnât know what he thought he knew about justice. Socrates rests his case, and then starts on someone else. This method can seem very negative, but if you want to end up with true beliefs, you have to test the ones you have very thoroughly, and Socratesâ contention was that, if you do so, youâll find that most of what you think is wrong.
3-SECOND THRASH
Ask questions, pick holes, and convince people they donât know what theyâre talking about.
3-MINUTE THOUGHT
Many have adopted what they call a âSocratic method,â although this often bears little resemblance to the highly negative approach of Socrates himself. Sometimes, the term is broadly used to refer to a rigorous examination of ideas by means of question and answer. Others in the practical philosophy movement have developed Socratic dialogue, in which the discussion is very democratic and cooperativeâutterly unlike the way in which Socrates destroyed the arguments of his interlocutors.
