Laudator Temporis Acti

Lucretius, On the Nature of Things 3.445-454 (tr. W.H.D. Rouse, rev. Martin F. Smith):

Besides, we feel that the mind is begotten along with the body, and grows up with it, and with it grows old. For as toddling children have a body infirm and tender, so a weak intelligence goes with it. Next, when their age has grown up into robust strength, the understanding too and the power of the mind is enlarged. Afterwards, when the body is now wrecked with the mighty strength of time, and the frame has succumbed with blunted strength, the intellect limps, the tongue babbles, the intelligence totters, all is wanting and fails at the same time.

praeterea gigni pariter cum corpore et una        445
crescere sentimus pariterque senescere mentem.
nam velut infirmo pueri teneroque vagantur
corpore, sic animi sequitur sententia tenvis;
inde ubi robustis adolevit viribus aetas,
consilium quoque maius et auctior est animi vis;        450
post ubi iam validis quassatum est viribus aevi
corpus et obtusis ceciderunt viribus artus,
claudicat ingenium, delirat lingua, <labat> mens,
omnia deficiunt atque uno tempore desunt.

453 labat add. Lachmann (vagat Palmer, meat Merrill)
