As beauty still has blemish; and the mind 170
The most accomplish’d its imperfect side;
Few bodies are there of that happy mould
But some one part is weaker than the rest:
The legs, perhaps, or arms refuse their load,
Or the chest labours. These assiduously, 175
But gently, in their proper arts employ’d,
Acquire a vigor and elastic spring
To which they were not born. But weaker parts
Abhor fatigue and violent discipline.
