"I would advise you not to expect too much happiness, even from the fulfillment of all your wishes. The moment you have distinguished yourself you become an object of envy and malice ; men whom you believed to be lovers of knowledge you will then find to be lovers only of fame, and haters of all knowledge that has not come from themselves. You will find that a life of science has in it no superiority to any other, unless it is pursued from a higher principle than the mere ambition of notoriety, and that demagogue or a philosopher differ only in the objects of their selfishness. As you will now have experienced how unsatisfying even the pursuit of knowledge is when insulated from higher objects, I hope, if you have not been fortunate enough to begin the study earlier, that you will devote yourself to the most extraordinary of all subjects, one which infinitely surpasses the mechanism of the heavens or the chemistry of the material world, the revelation of your duty and the destiny of man as contained in The Bible — a book which occupied the best hours of the manhood of Newton, of Locke, and of Euler."

“The human voice may be denominated the music of the mind; language, a figurative mode of expressing our ideas and sentiments. The effects of flowing from this beneficent endowment are overwhelming in contemplation and almost infinite in extent. It is principally instrumental to all the moral and physical improvements of man, and enables him to pour forth his otherwise invisible, inaudible, unfathomable thoughts, to his fellow-man and to his God.”

“It is a more rational belief that man may become a brute than that a brute may become a man; and it is an easier faith that plants and animals may dwindle down into an elemental atom, than that this atom should embrace in its organization, and evolve, all the noble forms of vegetable, animal, and intellectual life.”

“Though the large runt pigeon, with its massive beak and its huge feet, differs from its blue and barred progenitor the rock, it is a pigeon still. Though the slender Italian greyhound has a strange contrast with the short-legged bull-dog, they are both dogs in their teeth and in their skull. The mouse, even, has not been transmuted into the cat, nor the hen into the turkey, nor the duck into the goose, nor the hawk into the eagle, and still less the monkey into the man.”

“It is not within our province to inquire by what process, and in what condition the Almighty brought matter into existence-what the space was which it occupied, or what the forms were which it assumed. Of such things we know nothing. In the depths of primeval time, the globe we inhabit may have a planetary existence, wheeling along its ethereal railway without a breathing passenger to count its periods, and without a living plant to measure the day by its opening and closing blossoms, or to mark the rolling seasons by the yearly increments of its stem. Or it may have been the theatre on which vast cycles of animal and vegetable life have been run- now its birthplace, and now its grave: But we have no data to guide us in our conjectures, and even imagination fails us if we call it to our aid. Whatever may have been, had ceased to be at the commencement of our history, when the primary rocks, forming the moten nucleus of the globe, were first exposed to the action of the elements.”

“Amid the destructive convulsions of the physical world, even pious minds may have for an instant questioned the superintending providence of God. In the midst of famine, or pestilence, or war, they may have stood horror- struck at the scene. In the triumphs of fraud, oppression, and injustice, over honesty, and liberty, and law. Faith may have wavered, and Hope despaired; but in no condition, either of the physical or the moral world, does the mind question the POWER of its Maker. The omnipotence of the Creator, and the exertion of it in every corner of space, — His care over the falling sparrow, and His guidance of the gigantic planet, are the earliest of our acquired truths, and the very first that observation and experience confirm. When Reason gives wisdom to our perceptions, omnipotence is the grand truth which they inculcate. Whatever the eye sees, or the ear hears, or the fingers touch, — every motion of our body, every function it performs, every structure in its fabric, impresses on the mind, and fixes in the heart the conviction, that the Creator is all-powerful as well as all-wise. Omnipotence, in short, is the only attribute of God which is universally appreciated, which skepticism never unsettles, and which we believe as firmly when under the influence of our corrupt passions, as when we are looking devoutly to heaven. All the other attributes of God are inferences. His omnipresence, His omniscience, His justice, mercy, and truth, are the deductions of reason, and, however true and demonstrable, they exercise little influence over the mind; but the attribute of omnipotence predominates over them all, and no mind responsive to its power will ever be disturbed by the ideas which it suggests of infinity of time, infinity of space, and infinity of life.”

“The cultivation of science is a luxury of no common kind amid the bustle and vexation of life, and is quite compatible with the most active professional duties. Your education and the example you have had to copy will, I am sure, guard you against those presumptuous and skeptical opinions which scientific knowledge too often engenders. In the ardour of pursuit and under the intoxication of success scientific men are apt to forget that they are the instrument by which Providence is gradually revealing the wonders of creation, and that they ought to exercise their functions with the same humility as those who are engaged in unfolding the mysteries of His revealed will.”
