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. Th… - David Brewster

The history of the human species is the history of a variety of races in every stage of civilization and barbarism, and the great majority of which have neither an intellectual, nor a moral, nor a religious progressive history. Progression has not been the character of the history of man. Without alluding to his primeval fall from his high estate, we have only to cast our eyes over the globe, and look at the intellectual, moral, and religious catastrophes which it presents to us, — at ages of light and darkness, — at alternations of progress and decline, — at the highest civilization sinking into the lowest barbarism. Mark those eastern lands, now involved in darkness, from which the beams of knowledge first radiated on mankind. Study the extinction of morality in many regions of the earth where its great lessons were first taught by our Saviour and His apostles; and above all, mark the total suppression of the Christian faith in European communities, where it has been displaced by a religion whose doctrines were preached by conquest, and whose decalogue was dictated by the sword.

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.

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.
