Friedrich NietzscheIt is certainly not the least charm of a theory that it is refutable; it is precisely thereby that it attracts the more subtle minds.

Liberal institutions cease to be liberal as soon as they are attained: later on, there are no worse and no more thorough injurers of freedom than liberal institutions.
Friedrich NietzschePhysician, help yourself: thus help your patient too. Let this be his best help: that he may behold with his eyes the man who heals himself.
