Meno by Plato: on Daedalus and Automata

Socrates
Well, do you know why it is that you wonder, or shall I tell you?

Meno
Please tell me.

Socrates
It is because you have not observed with attention the images of Daedalus. But perhaps there are none in your country.

Meno
What is the point of your remark?

Socrates
That if they are not fastened up they play truant and run away; but, if fastened, they stay where they are.

From here.
