Yes lets revisit some basic definitions, Physics etymologically pertains to nature. Where Phy is to bring forth, produce, make to grow. In summary the summary of what has grown or been produced. Typically as with Newtonian Mechanics, it refers to solid body geometrical forms. Exists, Knowledge and Reality, fall more in the realm of Philosophy, the Love of Wisdom, or mental phenomena. Exists is anything that can be imagined, people typically require a description, and possibly previous experience, to imagine something, and agree, that it exists for them. Knowledge is previous experience. Real is an intersection of belief sets. Facts are elements of the real. True be personal experience. So what may be real for one group of people, may be false for another group of people. If the other group hasn't experienced. I.e. if group a has experienced computers, and group b does not, then computers are true for group a. ------------------------------------------- AGI Archives: https://www.listbox.com/member/archive/303/=now RSS Feed: https://www.listbox.com/member/archive/rss/303/21088071-c97d2393 Modify Your Subscription: https://www.listbox.com/member/?member_id=21088071&id_secret=21088071-2484a968 Powered by Listbox: http://www.listbox.com
