On the Life of the Wise Man made perfect by Instruction or, on the Unwritten Law, that is to say, on Abraham (11-15)

And he has very properly called his first volume, the Book of the Generation of the Real Man, speaking with perfect correctness; because the man who is full of good hope is worthy [*] [*]

If then any one were to reckon the generations, from the first man, who was made out of the earth, he will find him who, by the Chaldaeans is called Enos, and in the Greek language ἄνθρωπος (the man), to be the fourth in succession,

and in numbers the number four is honoured among other philosophers, who have studied and admired the incorporeal essences, appreciable only by the intellect, and especially by the all-wise Moses, who magnifies the number four, and says that it is "holy and praiseworthy;" [*] and the reasons for which this character has been given to it are mentioned in a former treatise.

And the man who is full of good hope is likewise holy and praiseworthy; as, on the contrary, he who has no hope is accursed and blameable, being always associated with fear, which is an evil counsellor in any emergency; for they say, that there is no one thing so hostile to another, as hope is to fear and fear to hope, and perhaps this may be correctly said, for both fear and hope are an expectation, but the one is an expectation of good things, and the other, on the contrary, of evil things; and the natures of good and evil are irreconcileable, and such as can never come together.

What has now been said about hope is sufficient; and nature has placed her at the gates to be a sort of doorkeeper to the royal virtues within, which no one may approach who has not previously paid homage to hope.
