"Self-respect is the cornerstone of all virtue."

“Were I to pray for a taste which should stand me in stead under every variety of circumstances, and be a source of happiness and cheerfulness to me during life, and a shield against its ills, however things might go amiss and the world frown upon me, it would be a taste for reading... Give a man this taste, and the means of gratifying it, and you can hardly fail of making him a happy man; unless, indeed, you put into his hands a most perverse selection of books. You place him in contact with the best society in every period of history,—with the wisest, the wittiest, the tenderest, the bravest, and the purest characters who have adorned humanity. You make him a denizen of all nations, a contemporary of all ages. The world has been created for him.”

“Unfortunately... the philosophy of Aristotle laid it down as a principle, that the celestial motions were regulated by laws proper to themselves, and bearing no affinity to those which prevail on earth. By thus drawing a broad and impassable line of separation between celestial and terrestrial mechanics, it placed the former altogether out of the pale of experimental research, while it at the same time impeded the progress of the latter by the assumption of principles respecting natural and unnatural motions, hastily adopted from the most superficial and cursory and remark, undeserving even the name of observation. Astronomy therefore continued for ages a science of mere record, in which theory had no part, except in so far as it attempted to conciliate the inequalities of the celestial motions with that assumed law of uniform circular revolution which was alone considered consistent with the perfection of the heavenly mechanism.”

“God knows how ardently I wish I had ten lives”

“The question "cui bono" to what practical end and advantage do your researches tend? is one which the speculative philosopher who loves knowledge for its own sake, and enjoys, as a rational being should enjoy, the mere contemplation of harmonious and mutually dependent truths, can seldom hear without a sense of humiliation. He feels that there is a lofty and disinterested pleasure in his speculations which ought to exempt them from such questioning; communicating as they do to his own mind the purest happiness of which human nature is susceptible, and tending to the injury of no one, he might surely allege this as a sufficient and direct reply to those who, having themselves little capacity, and less relish for intellectual pursuits, are constantly repeating upon him this enquiry.”

“What God sends is welcome.”

“Not to feel elevated on an occasion like the present, by this noble, this magnificent testimony of approbation of my friends, is not in human nature — at all events, it is not in my nature; but if any overweaning self-complacency might arise, and mix itself with my feelings at this moment, there is one consideration which would suffice to set it at rest for ever. . . The assembly, magnificent as it is, comprising in itself, as it does, the elite of everything that is illustrious in rank, talent, wealth, in the metropolis — this very assembly is a proof of the justice to which I have adverted I should be weak indeed, if I supposed that all this glorious array has reference to myself. No; it has reference to a far higher and more dignified object. I am but as one drop in the ocean. Every man of science will feel quite as much a sharer in the honors of the day, will feel quite as much distinguished by this assembly as I can be; for when, ere this, would it have been possible to collect together such an assembly as is around me to do honor to science, place it n preeminence, and crown it with distinction? This is, indeed, a new era — this is a memorable day for science, and every man who regards truth for its own sake will feel that on this occasion the eyes of the country are on him, and that England expects every man to do his duty! By that I have been able to accomplish in Africa, I have been amply rewarded; but I stand here not so much for anything of this nature, but as the representative of a class that is distinguished — of a principle which is triumphant; and I hope we shall never allow ourselves to forget the infinitely higher and more important circumstance, that it is the great truths of science, that it is the interpretation of God's great book of nature, and not the men who interpret these pages, that are the ultimate objects of all this praise.”
