The philosophy of science? Are you purposefully missing your irony? Are you saying my mind and senses are not real? Is the brain an actual physical organ, or is it an assumption? Is DNA a lie as well? You have to be joking around now.
For someone who claims to know something about science, I’m more than a little surprised that you are ignorant of the basic ASSUMPTIONS that the scientific method is based on. Don’t you realize that you have to ASSUME that reality exists outside of yourself for the scientific method to work?
