Reddit reviews Manhood of Humanity.

Completely randomly, I was reading up some book descriptions on Amazon, and stumbled upon something that fits my OP text:

> In 1921, Alfred Korzybski, a mathematician and scientist, classified Life with precise and accurate operational definitions of plants, animals, and humans. He defined the plants as energy-binders, the animals as space-binders, and we humans as time-binders. Korzybski explained that: The plants adapt to their environment through their awareness and control of energy. The animals adapt to their environment through their awareness and control of space. And we humans adapt to our environment through our awareness and control of time.

This is all true and might put a new perspective on things, but the categorization itself doesn't really explain anything. He simply took the major life groups and sorted them into named categories. And people can read the book (I probably will to, at one time, to see what it's all about), and believe they have gained lots of insight. But the categorization I see in the description doesn't really tell us anything about the phenomena described, it just gives them more names. Something Richard Feynman famously complained about.
