Who Were the Presocratic Philosophers? Our understanding of the Presocratics is complicated by the incomplete nature of our evidence. Instead, we are dependent on later philosophers, historians, and compilers of collections of ancient wisdom for disconnected quotations fragments and reports about their views testimonia. In some cases, these sources had direct access to the works of the Presocratics, but in many others, the line is indirect and often depends on the work of Hippias, Aristotle, Theophrastus, Simplicius, and other ancient philosophers who did have such access.

His famous claim that an idividual can and cannot step into the same river twice reveals an interest in criteria of unity and identity; even though all material constituents have undergone change, it is still, in a sence, the same river.

Preoccupied with change, he declared that fire is the central element of the universe, and he postulated a world with no beginning and no end Pythagoras - Greek philosopher and mathematician; held that numbers were basic to matter; the Pythagorean Theorem is named for his geometric formulation; developed atomic theory; students of his philosophy emphasized geometrical form as a basic property of atoms; developed mathematical relationships which led to musical harmony.

Empedocles - Some suggest c. To account for real change, he assumed that there must be more than one kind of matter, and he postulated four roots as elements; earth, air, fire, and water. Love and hate were considered principles of attraction and repulsion that alternately dominated the universe in a recurring cycle.

Leucippus - proposed an atomic concept of matter. Plato - Greek philosopher; pupil of Socrates; dealt with the nature of the universe; developed atomic theory of chemical change; ascribed geometric forms composed of bounding planes to the elements of earth, fire, air and water based upon their physical properties; held that elements could convert into one another through rearrangement of bounding planes; used deductive reasoning as a learning method.

Aristotle - updated engraving; Greek philosopher, educator and scientist; undertook a large-scale classification of plants and animals; introduced a method of scientific thinking that still plays a role today.

Epicurus - Greek philosopher; founded the system known as Epicureanism. He studied with followers of Plato and Democritus before opening his school in Athens.

The school, later called the Garden, accepted women and slaves. This, coupled with Epicurus' teachings concerning pleasure, led to public criticism of the school as a scene of debauchery. In reality, life there was fairly austere. Most of the writings of Epicurus have been lost.

Fragments from his most important work, Peri physeos On Naturewere recovered from the charred papyri of Herculaneum, buried by an eruption of Vesuvius in AD Zeno of Cition - Greek philosopher; founded the Stoic school of philosophy which held that matter, space, etc.A physicist is a scientist who specializes in the field of physics, which encompasses the interactions of matter and energy at all length and time scales in the physical universe.

Physicists generally are interested in the root or ultimate causes of phenomena, and usually frame their understanding in mathematical tranceformingnlp.comists work across a wide range of research fields, spanning all length.
