Nietzsche, Human, All Too Human:
Love as artifice. — Whoever wants really to get to know something new (be it a person, an event, or a book) does well to take up this new thing with all possible love, to avert his eye quickly from, even to forget, everything about it that he finds inimical, objectionable, or false. So, for example, we give the author of a book the greatest possible head start, and, as if at a race, virtually yearn with a pounding heart for him to reach his goal. By doing this, we penetrate into the heart of the new thing, into its motive center: and this is what it means to get to know it. Once we have got that far, reason then sets its limits; that overestimation, that occasional unhinging of the critical pendulum, was just a device to entice the soul of a matter out into the open.
When I attribute inspirational value to works of literature, I mean that these works make people think there is more to this life than they ever imagined. … Inspirational value is typically not produced by the operations of a method, a science, a discipline, or a profession. It is produced by the individual brush strokes of unprofessional prophets and demiurges. You cannot, for example, find inspirational value in a text at the same time that you are viewing it as the product of a mechanism of cultural production. To view a work in this way gives understanding but not hope, knowledge but not self-transformation. For knowledge is a matter of putting a work in a familiar context — relating it to things already known. … If it is to have inspirational value, a work must be allowed to recontexualize much of what you previously thought you knew; it cannot, at least at first, be itself recontextualized by what you already believe. Just as you cannot be swept off your feet by another human being at the same time that you recognize him or her as a good specimen of a certain type, so you cannot simultaneously be inspired by a work and be knowing about it. Later on — when first love has been replaced by marriage — you may acquire the ability to be both at once. But the really good marriages, the inspired marriages, are those which began in wild, unreflective infatuation.
