HERACLITUS (Heracleitus) 500 B.C.
Greek philosopher who maintained that strife and change are natural conditions
of the universe, in which fire forms the basic material principle of an orderly universe.
In his system, God was neither a creator nor omnipotent
but was limited to an identification with the opposites, for example,
good and evil, hot and cold, and other opposites are similarly related. The soul
consists of fire and endures the same cycle of change that other things
death brings the soul's complete extinction.
He stated that a person could not step into the same river twice, because the
water continually changes, meaning that all things in the universe change
from one stage to the other. He also stated that without quarrels and
anger (opposites) there wouldn't be harmony in the world.
Mans character and morale is his fate and
«Γνώθι σ' αυτόν»
(gnothi s' eauton)=
learn who you are,
search in your conscience, and try to became emotionally a perfect human being.
