That by which we know good and evil.] _Krit._--You will hardly find the end of well-doing anywhere else, if you deny that it follows on doing scientifically or according to knowledge.[25] _Sokr._--But according to knowledge, of _what_? Of leather-cutting, brazen work, wool, wood, &c.? _ Krit._--No, none of these. _Sokr._--Well then, you see, we do not follow out consistently your doctrine--That the happy man is he who lives scientifically, or according to knowledge. For all these men live according to knowledge, and still you do not admit them to be happy. Your definition of happiness applies only to some portion of those who live according to knowledge, but not to all. How are we to distinguish which of them? Suppose a man to know every thing past, present, and future; which among the fractions of such omniscience would contribute most to make him happy? Would they all contribute equally? _Krit._--By no means. _Sokr._--Which of them then would contribute most? Would it be that by which he knew the art of gaming? _Krit._--Certainly not. _Sokr._--Or that by which he knew the art of computing? _Krit._--No. _Sokr._--Or that by which he knew the conditions of health? _Krit._--That will suit better. _Sokr._--But which of them most of all? _Krit._--That by which he knew good and evil.[26] [Footnote 25: Plato, Charm. 173 D.

Temperance is not the science of good and evil, and is of little service.]
