Wisdom from the Early Stoics, Zeno of Citium 51

There are also certain insoluble arguments: the Veiled Men, the Concealed, Sorites, Horned Folk, the Nobodies. . . . 

The Sorites is as follows: "It cannot be that if two is few, three is not so likewise, nor that if two or three are few, four is not so; and so on up to ten. But two is few, therefore so also is ten." . . . 

The Nobody argument is an argument whose major premise consists of an indefinite and a definite clause, followed by a minor premise and conclusion; for example, "If anyone is here, he is not in Rhodes; but there is some one here, therefore there is not anyone in Rhodes." . . . 

—Diogenes Laërtius, 7.82
