Currently Reading right now, though, I'm reading John Searle "Mind, Language And Society". So far he seems to be making a case for Enlightenment-era realism such as Thomas Reid, contrary to David Hume, the idea that certain processes in nature must correlate or the various fields of the natural sciences and social sciences cannot "hang together" as he states. Right now I just got done with the chapter on consciousness, he asserts that consciousness is the highest or a higher level of biological brain processes just as say, digestion is for the stomach and intestines. Later on, he used the metaphor of an automobile's different contraptions all the way down to the chemical reactions of CO2 to explain that there's a biological basis for all of it while asserting that we "cannot disprove consciousness" like we can disprove the sun "setting" (he alludes to the illusion of a setting sun as the rotation of the earth around the sun to say how it disappears on the horizon), so its not something that can be reduced further than appearances.
