Good and evil flow as an integrated unit?

Good and evil, fortune and misfortune, do they flow as an integrated unit?

An idea that I have been wondering about for a long time now.

An interesting quote by Alan Watts, a man who has studied many forms of philosophy formally, has an endless number of degrees in the subject:

"The whole process of nature is an integrated process of immense complexity, and it’s really impossible to tell whether anything that happens in it is good or bad — because you never know what will be the consequence of the misfortune; or, you never know what will be the consequences of good fortune."


In his book the Tao of Physics, physicist Fritjof Capra explains esoteric philosophies (Chinese and Indian).

One particular chapter in it, "THE UNITY OF OPPOSITES" caught my attention.
