Every known fact in natural science was divined by the presentiment of somebody, before it was actually verified.
Ralph Waldo EmersonLook sharply after your own thoughts. They come unlooked for, like a new bird seen on your trees, and, if you turn to your usual task, disappear; and you shall never find that perception again; never, I say-but perhaps years, ages, and I know not what events and worlds my lie between you and its return.
Ralph Waldo EmersonYou think that your silence on certain topics, perhaps in the face of injustice, or unkindness, or mean-spiritedness, causes others to reserve judgement of you. Far otherwise; your silence utters very loud: you have no oracle to speak, no wisdom to offer, and your fellow men have learned that you cannot help them. Doth not wisdom cry, and understanding put forth her voice? We would be well to do likewise.
Ralph Waldo Emerson
