Brief history of the brain and the soul how do we know? how do we think? how do we feel?

Karl Popper was the most famous philosopher of science who shocked the scientific community by destroying the idol of science, considering that science does not proceed in a horizontal line from ignorance to truth, and that all scientific knowledge is nothing more than a process of proving errors of previous ideas. Matthias Eckoldt's book (A Brief History of the Brain and Spirit) is the best evidence of that, because despite the great accumulation of knowledge produced by humans, there are still simple and fundamental questions that science hardly has an answer to. Take, for example, the question about the nature of life, such a question still troubles scientists, and debates are raised here and there when searching for the dividing line between life and inanimate matter. Since the discovery of DNA, humans have been in endless confusion; if DNA is the basis of all our biological traits, does it also carry the basis for our psychological traits?
