As a materialist, I have never understood the concept or why it is worth discussing unless you are religious and believe in souls or something. Our brains are biological organs, running according to the same physical and chemical principles as everything else. What else is there to discuss?
Maybe? It could be my Kindle? I don’t know? I don’t know why people end statements with question marks? For example, in this comment, none of these sentences is a question? So they shouldn’t end in a question mark? But people often write like this? It’s quite strange to me? Have a nice day?
