Thales of Miletus
Water as arche — the first recorded attempt to explain the cosmos through a single natural principle
Thales of Miletus is traditionally regarded as the first Greek philosopher: the first thinker to seek natural rather than mythological explanations for the constitution of the world. Aristotle reports that Thales held water (hydōr) to be the arche — the underlying principle of all things. No writings survive; everything we know of his thought comes from later doxographers, principally Aristotle, Theophrastus, and Diogenes Laertius. He is also credited with predicting a solar eclipse (traditionally dated to 585 BCE) and with several geometrical theorems.

Thales inaugurates the naturalist programme: explaining nature through natural principles rather than mythological narrative.
"Thales says the principle is water, for which reason he declared that the earth rests on water." (Aristotle, Metaphysics 983b)
Thales stands at the origin of the classical Greek philosophical tradition; he is the first of the Seven Sages and the first Milesian.
"Most of the earliest philosophers thought the principles which were of the nature of matter were the only principles of all things." (Aristotle, Metaphysics 983b)
By positing a material substratum (water) as the arche of all things, Thales is the founding figure of materialist monism in Western philosophy.
"All things are full of gods." (Thales, in Aristotle, De Anima 411a7; the material-hylozoist reading)
Thales's inquiry presupposes a realist orientation: there is an objective natural order accessible to rational investigation.
"Thales was the first to engage in physical enquiry." (Theophrastus, ap. Simplicius)
Internal Tensions
The hylozoist fragment ("all things are full of gods") sits uneasily with a straightforward materialist reading of water-as-arche. Whether Thales was a materialist monist or a panpsychist hylozoist remains debated.
I. Time
Thales presupposes an eternal natural order: water as arche implies an everlasting material substrate from which all things arise and to which they return. Linear, continuous, deterministic in the sense that natural processes follow lawlike regularities.
Attributes
II. Space
The earth rests on water; the cosmos is spatially extended and three-dimensional. Beyond that the tradition preserves little about Thales's spatial cosmology.
Attributes
III. Matter
Water is the arche — the single material substance underlying all things. Matter is conserved (it transforms but is not destroyed) and substantival.
Attributes
IV. Observer
The observer is an embodied human being who investigates nature through observation and reason. Thales is credited with astronomical prediction and geometrical demonstration, presupposing active rational inquiry.
Attributes
V. Energy
The transformations of water into other substances imply an energetic process; hylozoism ("all things are full of gods") suggests intrinsic activity in matter.
Attributes
VI. Information
No explicit information-theoretic doctrine. The doxographic tradition preserves Thales's thought only in fragmentary reports.
