The fact that things exist dependent on being merely designated does not mean that whatever our mind thinks up is real or that whenever we designate something with a term, it becomes that object. Thinking there are real people in the television doesn't mean there are, and calling a telephone "grapefruit" doesn't make it one.
Appearances are deceptive because we are too confident in what we know; it is better for us to question everything. Don’t let inevitable rejection discourage your journey beyond the surface.
