The aspects of things that are most important for us are
hidden because of their simplicity and familiarity. (One is unable to
notice something—because it is always before one’s eyes.) The real
foundations of his enquiry do not strike a man at all. Unless that fact
has at some time struck him.—And this means: we fail to be struck
by what, once seen, is most striking and most powerful.
