You will certainly not be able to take the lead in all things yourself, for to one man a god has given deeds of war, and to another the dance, to another lyre and song, and in another wide-sounding Zeus puts a good mind. - Homer
The kosmos works by harmony of tensions, like lyre and bow. Good and evil are one. On the one hand God sees all as well, fair, and good; on the other hand a human being sees injustice here, justice there. Justice in our minds is strife. We cannot help but see war makes us as we are. - Heraclitus
People do not know how what is at variance agrees with itself. It is an attunement of opposite tensions, like that of the bow and the lyre. - Heraclitus
