Heraclitus - Greek Philosopher
540–480 Creative and influential Heraclitus of Ephesus.
Heraclitus stands primarily for the radical thesis that'Everything is in flux',
like the constant flow of a river.
His great truth is that 'All things are one', but this unity, far from excluding difference, opposition and change, actually depends on them, since the universe is in a continuous state of dynamic equilibrium.
- Day and night,
- Up and down,
- Living and dying,
- Heating and cooling
- unity consists of opposites;
- remove day, and night goes too,
- just as a river will lose its identity if it ceases to flow.
