Chapter 2: RealityThe First Philosophers Introducing Philosophy, 10th edition Robert C. Solomon, Kathleen Higgins, and Clancy Martin
The First Greek Philosophers • Ancient philosophical traditions looked beyond ordinary experience for an understanding of “reality” • The first appeared in the middle of the first millennium B.C.E.
The Ionian Naturalists Pre-Socratics who lived in the sixth and fifth centuries B.C.E. in and around Greece: • Thales • Everything is water • Anaximander • Ultimate reality: apeiron • Anaximenes • Everything is air
Monism, Materialism, and Immaterial “Stuff” • Monism: the attempt to reduce all of the varied things in the world to one kind of thing • All monistic views rely on materialism: reality is ultimately composed of some kind of material "stuff"
Heraclitus • Conception of an immaterial “stuff”: fire • Fire represents flux or change • Change has a form that underlies all reality, called the logos
Democritus • Pluralist: more than one basic “stuff” makes up the universe • Universe is made up of tiny bits of stuff that he called atoms
Animism • All of these philosophers also believed in animism:all things, including rocks and animals, are living
Pythagoras • Pythagoras: numbers are the real nature of things • Reincarnation and immortality of the soul • Emphasis on logic and thought
The Appearance/Reality Distinction • Underlying reality thought to be quite different from how the world appears • Thales–all is composed of water • Democritus–the unchanging and indestructible atoms • Heraclitus–perpetual changing world also has logos
Parmenides • A monistic mathematician • Reality must be eternal and unchanging; therefore, the world of our experience cannot be real • The world of change should not be of interest to philosophy
The Sophists • Gorgias: there is no reality, and even if there were, we could not know anything about it • Protagoras: man is the measure of all things, meaning there is no reality except for what we take to be reality • Anticipated both pragmatism and relativism
Metaphysics • These various theories are called metaphysical doctrines • Ask and attempt to answer the most basic questions about the universe and the “stuff” of which it is composed • Aristotle called this stuff substance • Ontology–concerned with being • Cosmology–studies the universe
