Valerius Maximus 7.2.ext.12 (tr. D.R. Shackleton Bailey):
Shrewdly enough too said Anaxagoras to somebody who asked him who was the happy man: "None of those whom you think fortunate. You will find him in the number which you think to be made up of miserables." He will not abound in riches and offices, he will be a faithful, persevering cultivator of a small holding or of unpretentious learning, happier in the back row than the front.
nec parum prudenter Anaxagoras interroganti cuidam quisnam esset beatus 'nemo' inquit 'ex iis quos tu felices existimas, sed eum in illo numero reperies qui a te ex miseris constare creditur.' non erit ille divitiis et honoribus abundans, sed aut exigui ruris aut non ambitiosae doctrinae fidelis ac pertinax cultor, in recessu quam in fronte beatior.
