This is a busy world running behind money who dare to think of their minds. What if its an illusion, the wall we see when we woke up, the people you see around, the money that you grab, the tech you used to read this, seems all a mystery.
Each one of this can only be sure in his own minds.Reality is not as obvious and simple as we like to think. Since the dawn of Newtonian science with its vision of simple mechanical principles governing the entire universe, some philosophers have been tempted by the idea that consciousness could be explained in purely physical terms.Things that we accept as true are notoriously wrong scientists and philosophers have made every effort to change our common perceptions of it.
Objects can only exist as a phenomenon of consciousness. So,your smartphone or laptop a is only here while you see or aware of it,but what happens when you turn around ?
