Wilson's proposal is ambitious, at least judging by the title. However, to understand what he means, one has to get the straighten out our causality thinking about what it means to talk about existence — not in an empty (i.e. non-empirical) ideological way, but taking the hard evidence of the natural sciences and then, only then, think about existence.

This is Wilson's proposal. The book is well written, with good examples and with a narrative that is not too demanding to follow. Since life is what it is, and that is truly the only acceptable starting point to discuss The Meaning of Human Existence, in that sense, Wilson is right in trying to tackle such a long and difficult discussion through the biological lens. Wilson does not offer an answer — he wants to open the way to a more fruitful discussion.

If you prefer to swallow the blue pill of whatever dream narrative it best suits your interests, this is not the book for you. On the other hand, if you choose the red one, you have to face the crudeness of how things truly are — only then you can start to think about The Meaning of [your] Human Existence — and this book is probably well suited for you.
