Hor. lib. i. Ode iv. 10.
The man within the golden mean
Who can his boldest wish contain,
Securely views the ruin'd cell,
Where sordid want and sorrow dwell;
And in himself serenely great,
Declines an envied room of state.
Francis.
Among many parallels which men of imagination have drawn between the natural and moral state of the world, it has been observed that happiness, as well as virtue, consists in mediocrity; that to avoid every extreme is necessary, even to him who has no other care than to pass through the present state with ease and safety; and that the middle path is the road of security, on either side of which are not only the pitfalls of vice, but the precipices of ruin.
Thus the maxim of Cleobulus the Lindian, μετρον αριστον, Mediocrity is best, has been long considered as an universal principle, extended through the whole compass of life and nature. The experience of every age seems to have given it new confirmation, and to shew that nothing, however specious or alluring, is pursued with propriety, or enjoyed with safety, beyond certain limits.
