Limited as we are in every way, this state which holds the mean between two extremes is present in all our impotence. Our senses perceive no extreme. Too much sound deafens us; too much light dazzles us; too great distance or proximity hinders our view. Too great length and too great brevity of discourse tend to obscurity; too much truth is paralysing (I know some who cannot understand that to take four from nothing leaves nothing). First principles are too self-evident for us; too much pleasure disagrees with us. Too many concords are annoying in music; too many benefits irritate us; we wish to have the wherewithal to over-pay our debts. Beneficia eo usque læta sunt dum videntur exsolvi posse; ubi multum antevenere, pro gratia odium redditur.[1] We feel neither extreme heat nor extreme cold. Excessive qualities are prejudicial to us and not perceptible by the senses; we do not feel but suffer them. Extreme youth and extreme age hinder the mind, as also too much and too little education. In short, extremes are for us as though they were not, and we are not within their notice. They escape us, or we them.
This is our true state; this is what makes us incapable of certain knowledge and of absolute ignorance. We sail within a vast sphere, ever drifting in uncertainty, driven from end to end. When we think to attach ourselves to any point and to fasten to it, it wavers and leaves us; and if we follow it, it eludes our grasp, slips past us, and vanishes for ever. Nothing stays for us. This is our natural condition, and yet most contrary to our inclination; we burn with desire to find solid ground and an ultimate sure foundation whereon to build a tower reaching to the Infinite. But our whole groundwork cracks, and the earth opens to abysses.
Let us therefore not look for certainty and stability. Our reason is always deceived by fickle shadows; nothing can fix the finite between the two Infinites, which both enclose and fly from it.
If this be well understood, I think that we shall remain at rest, each in the state wherein nature has placed him.
