Moral Letters to Lucilius Section 5

Puta enim duo aedificia excitata esse, ab imo disparia, aeque excelsa atque magnifica. Alterum puram aream accepit; illic protinus opus crevit. Alterum fundamenta lassarunt in mollem et fluvidam humum missa multumque laboris exhaustum est, dum pervenitur ad solidum. Intuenti ambo quicquid fecit alter in aperto est, alterius magna pars et difficilior latet.

Figure-toi deux édifices pareils en tout, égaux en hauteur et en magnificence : l’un, établi sur un sol ferme, s’est rapidement élevé ; l’autre a de vastes fondations jetées sur un
sol mou et sans consistance, et il en a coûté de longs efforts pour arriver à la terre solide. On voit dans le premier tout ce qui a été fait ; la plus grande et la plus difficile partie du second est cachée.

Suppose that two buildings have been erected, unlike as to their foundations, but equal in height and in grandeur. One is built on faultless ground, and the process of erection goes right ahead. In the other case, the foundations have exhausted the building materials, for they have been sunk into soft and shifting ground and much labour has been wasted in reaching the solid rock. As one looks at both of them, one sees clearly what progress the former has made, but the larger and more difficult part of the latter is hidden.
