Accounts Quote by Gerald Fischbach
“The brain immediately confronts us with its great complexity. The human brain weighs only three to four pounds but contains about 100 billion neurons. Although that extraordinary number is of the same order of magnitude as the number of stars in the Milky Way, it cannot account for the complexity of the brain. The liver probably contains 100 million cells, but 1,000 livers do not add up to a rich inner life.”

He highlights the brain’s immense complexity, noting that sheer neuron count or organ size cannot fully explain consciousness or mental richness.
In simple terms: The brain is hugely complex, more than just many cells.

A Different Perspective
Complexity may be overstated; other factors shape cognition.
![“As David Eagleman describes it in his wonderful book Incognito: Your brain is built of cells called neurons and glia—hundreds of billions of them. Each one of them is as complex as a city. . . . The cells [neurons] are connected in a network of such staggering complexity that it bankrupts human…” quote by Ray Dalio](https://sms4smile.com/quotes/img-quotes/cdf/ray-dalio-299_books_as-david-eagleman-describes-it-in-his-wo_2804625.jpg)
