Thomas Taylor,
Introduction to the Philosophy and Writings of Plato
“ It is well said indeed by Lysis, the Pythagorean, that to inculcate liberal speculations and discourses to those whose morals are turbid and confused, is just as absurd as to pour pure and transparent water into a deep well full of mire and clay; for he who does this will only disturb the mud, and cause the pure water to become defiled. ”
