"True humility, therefore, never knows that it is humble, as I have said; for if it knew this, it would turn proud from contemplation of so fine a virtue.
But it clings with all its heart and mind and senses to lowly things, sets them continually before its eyes, and ponders them in its thoughts. And because it sets them before its eyes, it cannot see itself nor become aware of itself, much less of lofty things.
False humility, on the other hand, never knows that it is proud; for if it knew this, it would soon grow humble from contemplation of that ugly vice. But it clings with heart and mind and senses to lofty things, sets them continually before its eyes, and ponders them in its thoughts. And because it does this, it cannot see itself nor become aware of itself. Hence honors come to it not unawares nor unexpectedly, but find it immersed in thoughts of them. But dishonor and humiliation take it unawares and when it is thinking of something far different.
It is in vain, therefore, to teach men to be humble by teaching them to set their eyes on lowly things, nor does any one become proud by setting his eyes on lofty things. Not the things, but our eyes, must be changed; for we must needs spend our life here in the midst of things both lowly and lofty." -
Martin Luther, Commentary on the Magnificat.
