Context

“Such persons vaunt about not lying: but inability to lie is still far from being love to truth. Be on your guard!
Freedom from fever is still far from being knowledge! Refrigerated spirits I do not believe in. He who cannot lie, doth not know what truth is.
10.
If ye would go up high, then use your own legs! Do not get yourselves CARRIED aloft; do not seat yourselves on other people's backs and heads!
Thou hast mounted, however, on horseback? Thou now ridest briskly up to thy goal?” source
