Earliest first known philosopher
Primarily he wanted to know what was the principle behind
nature.
What was it made of and how was it made.
Believed that the universe was controlled by fixed laws
All things are made up of water.The earth floats on water.
All life originated from the hydro and turn into water again.
He measured the height of pyramid by shadow.
Introduced deductive science, by means of logic.
First attempt to explain the universe on scientific principles.
Thales of Miletus
636-546 B.C.
sna.syednomanali@gmail.com 6
∗ He made first map of the world.
∗ Worlds are made up of apeiron, a boundless place where
things are evolved and dissolved.
∗ Aperion is neither hot or cold,nor wet or dry,it is neutral.
∗ All creation of life is because of some change in nature.
∗ Idea of inherent quality arise.Changes of quantity into
quality.
Anaximander
610-546 B.C.
sna.syednomanli@gmail.com 7
∗The earth does not move in cylindrical shape.
∗The earth was motionless and moved by opposite
forces.
∗Sea is the begetter of winds. Everything is air
∗Air is in constant motion in the method of :
ocondensation – increase in density (turns into earth).
orarefaction – decrease in density (clouds & fire).
∗The earth is on air surrounded by celestial bodies.
Anaximenes
570-526 B.C.
sna.syednomanli@gmail.com 8
∗ All things are number in ratio and proportions.
∗ The universe could only be understood through numbers.
∗ Number 1 is point,2 is line 3 is surface & 4 is solid.
∗ Line is infinite divisible so space is in infinite
∗ Things are in opposites odd and even ,plus and minus.
∗ Established deductive reasoning with axiom 2 + 2 = 4.
∗ Famous for the Pythagorean Theorem: a2
+ b2
= c2
∗ discovered music is governed with the principle of math.
Pythagoras
582-500 B.C.

Heraclitus
540-480B.C
∗ Everything is flux , a change of nature.
∗ There is no being just becoming.
∗ We cannot step twice into the same river.
∗ Our sense perception are reliable source.
∗ The nature force is fire.
∗ The world is characterized by two opposites.
∗ Teach “unity of opposites” dark and light are the form
of temperature.
∗ The road up and down are the one and same.
sna.syednomanli@gmail.com 10
∗ Nature is constant which is one .
∗ Change in nature are delusion. Reality is single.
∗ Change become something,something become nothing.
∗ Something exist it is said it cannot exist (it is not)
∗ Multiplicity occur due to our senses that gives illusion.
∗ What is, is; what is not, is not. Change requires motion.
∗ Motion requires empty space. Empty space is not.
∗ Therefore, Nothing ever changes or can change.
Parmenides
540-480 B.C
sna.syednomanli@gmail.com 11
∗ He was the father of inorganic chemistry
∗ He believed that both Parmenides and Heraclitus are right
∗ Nothing changes means water could not be destroyed.
∗ Nature changes means we believe what we see
∗ First to suggest all four root of nature
∗ Air-water-earth-fire
∗ Two opposites nature force to unite : love and strife
∗ Love attract and hate separate these 4 elements.
∗ Perception is affected by imbalance of these four elements.
∗ Eye consists of all these four element to see.
∗ Thought is physical,man is upset by changes in 4 elements.
Empedocles
490-430 B.C.
sna.syednomanli@gmail.com 12
∗ Motion and changes are possible.
∗ There are no basic 4 elements ,they are unlimited .
∗ Nous ,mind (intellect) is a force which is infinite.
∗ Mind is immaterial that animates all living thing.
∗ The world is built of seeds that is indivisible
∗ Mind is there where everything else is others.
∗ a skin cell contain nucleus reveal hair,body i-eDNA
Anaxagoras
500-428 B.C
sna.syednomanli@gmail.com 13
∗ On his concept, the atomic theory was developed.
∗ the universe came in atom that are indivisible particles.
∗ Atom has size ,shape ,motion,color and heat.
∗ Nothing beyond the natural order.
∗ There is Only two things, atoms and empty space.
∗ The atoms move is space which is uncountable.
∗ Man is the micro organism of the universe.
Democritus
460?- 360 B.C
sna.syednomanli@gmail.com 14
∗Man is the measures of all things of what are

∗Most famous of the Sophists who teach to elite.
∗The sophist have encyclopedic knowledge.
∗Teachings to equip citizens for life ie -art of rhetoric
∗Concept of Relativism :each one has own truth.
∗Might is right –everything is relative.
∗Both people speak truth at same time.
∗We communicate in symbols & no one symbolize same.
