Why Does the Flux Doctrine Go Along With Relativism About Truth?

The way things seem to me determines the way the wind is and isn't for me. Socrates adds that theotetus and protagoras have another heavy hitter on their side, namely the presocratic philosopher heraclitus. But why does the flux doctrine go along with relativism about truth? i know what you're thinking. H socrates has a couple of other tricks up his sleeve. He starts with abuse. Wouldn't it be just as true to say that a pig or a baboon is the measure of all things? The argument doesn't carry much weight. Fortunately he has more philosophically satisfying points to make too.
