Context: It is altogether reasonable to conclude that the heavenly bodies, alias worlds, which move or are situate within the circle of our knowledge, as well all others throughout immensity, are each and every one of them possessed or inhabited by some intelligent agents or other, however different their sensations or manners of receiving or communicating their ideas may be from ours, or however different from each other. For why would it not have been as wise or as consistent with the perfections which we adore in God, to have neglected giving being to intelligence in this world as in those other worlds, interspersed with another of various qualities in his immense creation? And inasmuch as this world is thus replenished, we may, with the highest rational certainty infer, that as God has given us to rejoice, and adore him for our being, he has acted consistent with his goodness, in the display of his providence throughout the university of worlds.

Context: To read a newspaper is to refrain from reading something worth while. The natural laziness of the mind tempts one to eschew authors who demand a continuous effort of intelligence. The first discipline of education must therefore be to refuse resolutely to feed the mind with canned chatter.
People tell me that they must read the papers so as to know what is going on. In the first place, they could hardly find a worse guide. Most of what is printed turns out to be false, sooner or later. Even when there is no deliberate deception, the account must, from the nature of the case, be presented without adequate reflection and must seem to possess an importance which time shows to be absurdly exaggerated; or vice versa. No event can be fairly judged without background and perspective.
