To get everything you want is not a good thing. Disease makes health seem sweet. Hunger leads to the appreciation of being full-fed. Tiredness creates the enjoyment of resting
HeraclitusOf the Logos which is as I describe it men always prove to be uncomprehending, both before they have heard it and when once they have heard it. For although all things happen according to this Logos, they [men] are like people of no experience, even when they experience such words and deeds as I explain, when I distinguish each thing according to its constitution and declare how it is; but the rest of men fail to notice what they do after they wake up just as they forget what they do when asleep.
HeraclitusWhosoever wishes to know about the world must learn about it in its particular details. Knowledge is not intelligence. In searching for the truth be ready for the unexpected. Change alone is unchanging. The same road goes both up and down. The beginning of a circle is also its end. Not I, but the world says it: all is one. And yet everything comes in season.
