Can anyone explian Heraclitus doctrine of opposites and change also role of Fire and Logos?

Answer 1

Everything is fire, but there is a logic to the flame.

The fire is metaphoric, it just means everything changes. Nothing is certain but change. You are not the same person you were yesterday. The only permanence is the Logos, the rules for change.

Heraclitus is intriguing. His Logos sounds very much like Newton's laws of Physics. His 'Everything is Fire' sounds much like Einstein's 'E=mc^2' i.e. everything is energy.

I am unclear on his doctrine of opposites, but I suspect it was some sense that change is driven by opposing forces.
That opposites were intrinsic to the nature of things.
