Heraclitus

I just finished reading a book about Heraclitus (c. 500bc). Quite interesting. His theory was that, as he says, "Good and bad are the same". This means that without one thing, you cannot have another. You have to experience the bad to know you have the good. Another fragment of his work I like is "It makes more sense to throw out a corpse than manure." I feel this means that you shouldn't hold on to the past or the broken; but keep things that are functional and will help you, just like manure helped the ancient Greeks sow their fields. Also, "The sun is new each day". This isn't very hard to understand because there are many sayings that echoes its meaning today, but the fact that you should take every day as a new adventure is a great way to live life.
