Topic 2: Reality

Reality, in everyday usage, means "the state of things as they actually exist." In one sense it is what is real;[1] in its widest sense, the term reality includes everything that is, whether or not it is observable or comprehensible. Reality in this sense includes being and sometimes is considered to include nothingness, where existence is often restricted to being (compare with nature).
