An intellectual and hypothesizing analysis of the evolution of the human mind. Carl Sagan has great prose but is sometimes a little too boggled down with technical terminology that his intended audience "the layman" might have some difficulty. It is an interesting read. I am more on the Gould camp (that human intelligence appeared out of chance and if you reset the cosmic clock we might not be here and our definition of intelligence might never exist) in regards to the evolution of human intelligence but I enjoyed it nonetheless. "Science is only the Latin word for knowledge...Knowledge is is our destiny."

One of the lesser points Sagan introduces is the analytical check our "left" brain must impose on our "right" brain's more intuitive connections. Ironically I would argue that Sagan's hesitance to check himself was this book's biggest failure. Often he excitedly drew out connections, usually preceded by a phrase such as "I wonder," that do not stand his left-brained test of reason.

With that said, I found the book worth the read. Sagan draws up a quick tour of human evolutionary lineage with a focus on our neocortical developments. He also always had a ready comparison to primates in order to more
fully showcase what makes us "human". As always, the line is thinner and more vague than many more orthodox religions would like to believe.

One major takeaway was the human ability, through the development of the neocortex, to have built-in "intelligence", I.e. analytical thinking, as compared to "instinct". Whereas instinctual information is programmed into tightly packed DNA (and is therefore limited in nature) and survives solely off adaptive selection, intelligence (or extragenetic info) resides in a larger brain capacity.. it is the ability to think on the fly and respond successfully to innumerable changing environments and situations.

Sagan introduces many other varying ideas and usually does a good job supporting them scientifically. All in all, if you ignore anything he says about aliens or computers, it's a good read. ( )

Very good considering that Carl Sagan is writing outside of his field. Great speculations on the evolution of human/animal intelligence. Minus 1 star for being heavily outdated (originally published in 1977). I'll definitely be reading a more recent book on the same topic; written by a neuroscientist rather than an astrophysicist. ( )

I kind of thought this was going to be -- I don't know, something about mythology. Like, Jungian myth, maybe. So I shouldn't judge it for not being the book I wanted to read, but... ( )

Populair wetenschappelijke uiteenzetting over het menselijk brein. Het beschrijft de evolutie van de hersenen, de uit verschillende perioden stammende lagen, de verschillen tussen de linker- en de rechterhelft, en vergelijkt de menselijke intelligentie met enerzijds dierlijke, anderzijds kunstmatige. Het is goed leesbaar, redelijk betrouwbaar, niet erg overzichtelijk, en wekt met literaire middelen een indruk van visie die de inhoud niet waarmaakt. Bevat woordenlijst bibliografie en register. Zwart-wit illustraties.
