Heraclitus

Heraclitus ( c. 540 BC – c. 480 BC) was a Greek philosopher, born at Ephesus. He criticized his predecessors and contemporaries for their failure to see the unity in experience. He was the first western philosopher who went beyond the physical existence to metaphysical and moral theories, and was the first to note how everything throughout the universe is in constant flux, and nothing permanent but in transition from being to nothing and from nothing to being, from life to death and from death to life, that nothing is, that everything becomes, that the truth of being is becoming, that no one, nothing, is exempt from this law, the law symbolised by the fable of the Phoenix in the Fire.

  • Of the logos (words, speech, discourse, or meaning) being forever do men prove to be uncomprehending, both before they hear and once they have heard it.
