Human existence is girt round with mystery: the narrow region of our experience is a small island in the midst of a boundless sea. To add to the mystery, the domain of our earthly existence is not only an island of infinite space, but also in infinite time. The past and the future are alike shrouded from us: we neither know the origin of anything which is, nor its final destination.
John Stuart MillHe who knows only his own side of the case (argument) knows little of that. His reasons may be good, and no one may have been able to refute them. But if he is equally unable to refute the reasons on the opposite side, if he does not so much as know what they are, he has no ground for preferring either opinion
John Stuart MillExperience has taught me that those who give their time to the absorbing claims of what is called society, not having leisure to keep up a large acquaintance with the organs of opinion, remain much more ignorant of the general state either of the public mind, or of the active and instructed part of it, than a recluse who reads the newspapers need be.
