Life without an Education

Instrue praeceptis animum, ne discere cessa;
nam sine doctrina vita est quasi mortis imago

Build up your mind with lessons, never cease learning;
for life without education is an echo of death.

Dicta Catonis 3.1.

Otium sine litteris mors est et hominis vivi sepultura

Free time without literature is death and burial for a living man

Seneca, Ep. Mor. 82.3.

ἐρωτηθεὶς τίνι διαφέρουσιν οἱ πεπαιδευμένοι τῶν ἀπαιδεύτων, "ὅσῳ," εἶπεν, "οἱ ζῶντες τῶν τεθνεώτων."

When asked how the educated differ from the uneducated, [Aristotle] answered "as much as the living from the dead."

Diogenes Laertius 5.19.
