Not that you lied to me but that I no longer believe you has shaken me. - Friedrich Nietzsche

They muddy the water, to make it seem deep.

While the noble man lives in trust and openness with himself (gennaios 'of noble descent' underlines the nuance 'upright' and probably also 'naïve'), the man of ressentiment is neither upright nor naive nor honest and straightforward with himself. His soul squints; his spirit loves hiding places, secret paths and back doors, everything covert entices him as his world, his security, his refreshment; he understands how to keep silent, how not to forget, how to wait, how to be provisionally self-deprecating and humble. A race of such men of ressentiment is bound to become eventually cleverer than any noble race; it will also honor cleverness to a far greater degree: namely, as a condition of existence of the first importance; while with noble men cleverness can easily acquire a subtle flavor of luxury and subtlety — for here it is far less essential than the perfect functioning of the regulating unconscious instincts or even than a certain imprudence, perhaps a bold recklessness whether in the face of danger or of the enemy, or that enthusiastic impulsiveness in anger, love, reverence, gratitude, and revenge by which noble souls have at all times recognized one another. Ressentiment itself, if it should appear in the noble man, consummates and exhausts itself in an immediate reaction, and therefore does not poison: on the other hand, it fails to appear at all on countless occasions on which it inevitably appears in the weak and impotent.

To learn to see- to accustom the eye to calmness, to patience, and to allow things to come up to it; to defer judgment, and to acquire the habit of approaching and grasping an individual case from all sides. This is the first preparatory schooling of intellectuality. One must not respond immediately to a stimulus; one must acquire a command of the obstructing and isolating instincts.
