Appearances to the mind are of four kinds. Things either are what they appear to be; or they neither are, nor appear to be; or they are and do not appear to be; or they are not, and yet appear to be. Rightly to aim in all these cases is the wise man’s task.
— Epictetus (c. 50-120 A.D.), Greek stoic philosopher
