Until the 17 century science and philosophy were not regarded as separate disciplines.

From 7th century B. C. up to the beginning of 6th century A. D From 7th century B. C. up to the beginning of 6th century A. D. in Ancient Greece, there was a specific philosophical learning which combined the traditions of the East, Greek mythology, art and early sciences. Now (from 6th 5th centuries B. C.) it became possible to identify a common base (for all different trends and schools of the ancient philosophy).

Natural philosophy term used for the branch of philosophy that sought to understand the fundamental structure and nature of universe, whether by theoretical or experimental methods.

they were, in effect, the first Western scientists. Early Greek thinkers 'pre-Socratics', who developed theories to explain the nature of things, based оn their observation of the natural world; they were, in effect, the first Western scientists.

Thales of Miletus (6th century ВСЕ) is generally regarded as the first philosopher and scientist. Не mistakenly thought that fundamental element was water.

Comment Only оne oxygen atom separates Thales from modeгn physics, for we now consider all substances ultimately to be derived from hydrogen.  

Heraclitus born c. 540 BC, , Ephesus, in Anatolia died c. 480 argued that everything is in a state of flux and that even those things that appear to be permanent are in fact subject to a process of change. ‘You cannot step into the same river twice’.

Heraclitus In his cosmology fire forms the basic material principle of an universe.

Heraclitus We live now in а world where most people take it for granted that everything from galaxies, stars and species to the cells that make up our bodies are in а constant process of change and development. But Heraclitus came to this view by observation and logic, while those around him saw the created order as static.

Anaximander (circa 611-c. 547 bc) inventing cartography disciple and friend of Thales Taught that apeiron (Greek infinite) held that all things eventually return to the element from which they originated.

Anaximenes (circa 570-500 bc), Ionian school he held that air is the primary element to which everything else can be reduced.

Pythagoras (582?-500?bc) Greek philosopher and mathematician, whose doctrines strongly influenced Plato.

Theory of numbers of the Pythagoreans they cultivated the concept of number, which became for them the ultimate principle of all proportion, order, and harmony in the universe. They believed that all things are numbers «4» – agreement and friendship «5» – wealth and welfare «10» - the universe

The astronomy of the Pythagoreans for they were the first to consider the earth as a globe revolving with the other planets around a central fire.

Leucippus and Democritus (from the 5th century ВСЕ) developed the theory (atomism) that all matter was comprised of very small particles separated by empty space.

Archimedes (287-213 ВСЕ). Не is perhaps best known for his bath, from which he leapt shouting 'Eureka! Eureka!'

His task was to find if а crown was made of pure gold or if it had been debased. By observing how water was displaced as be got into his bath, be had а simple method of measuring volume - by measuring the volume of water displaced when the crown was immersed in а container full of water.

Notice the logic used by these early thinkers. Тhay saw that а substance can take оn different forms - solid, liquid or gas, depending оn temperature (as when water boils or freezes) - and came to the general principle that the same atoms combine differently at different temperatures.  

In observing the world, looking for explanations for what they saw and moving from these to formulate general theories, these early philosophers were doing what we today recognize as science. Тhay had intuition in plenty; what they lacked was anу systematic or experimental method.

Socrates born c. 470 BC, Athens died 399 BC, Athens

Socrates philosopher credited as one of the founders of Western philosophy. He is an enigmatic figure known chiefly through the accounts of classical writers, especially the writings of his students Plato and Xenophon.

The Death of Socrates Jacques-Louis David 1787

Plato 428/427 or 424/423 – 348/347 BCE) Plato, who argued that the things we see and experience around us are merely copies of eternal but unseen realities.

Plato I only know that this creature before me is а dog, because I have an intuition of 'dogginess' in general.

In his famous analogy of the cave (in The Republic), most people see nо more than fleeting images, shadows cast upon the back wall of а cave by аn unseen fire. Only the philosopher turns to see beyond the fire, to objects themselves, and then, up through the mouth of the cave, to the light of the sun.

Comment This view, which has been immensely influential in Western thought, tends to separate оff the mind from the physical world of experience. It looks outside the world for its reason and its meaning, so that the things we see have less interest for us than do the theories we have of them.

Aristotle (384-322 ВСЕ) argued that knowledge of the world comes through experience interpreted by reason; you need to examine phenomena, not turn away from them classification divided up living things into their various species and genera

Aristotle argued that а thing had four different causes: Its material cause is the physical substance out of which it is made. Its formal cause is its nature, shape or design – that which distinguishes а statue from the material block of marble from which it has been sculpted. Its efficient cause is that which brought it about – our usual sense of the word 'cause'. 4 Its final cause is its purpose or intention.
