Now it is an unquestionable fact that those who are equally acquainted with, and equally capable of appreciating and enjoying, both, do give a most marked preference to the manner of existence which employs their higher faculties. Few human creatures would consent to be changed into any of the lower animals, for a promise of the fullest allowance of a beast’s pleasures; no intelligent human being would consent to be a fool, no instructed person would be an ignoramus, no person of feeling and conscience would be selfish and base, even though they should be persuaded that the fool, the dunce, or the rascal is better satisfied with his lot than they are with theirs. They would not resign what they possess more than he, for the most complete satisfaction of all the desires which they have in common with him. If they ever fancy they would, it is only in cases of unhappiness so extreme, that to escape from it they would exchange their lot for almost any other, however undesirable in their own eyes. A being of higher faculties requires more to make him happy, is capable probably of more acute suffering, and certainly accessible to it at more points, than one of an inferior type; but in spite of these liabilities, he can never really wish to sink into what he feels to be a lower grade of existence.
The publication of Darwin’s The Origin of Species in 1859 marked a dramatic turning point in scientific thought. The volume had taken Darwin more than twenty years to publish, in part because he envisioned the storm of controversy it was certain to unleash. Indeed, selling out its first edition on its first day, The Origin of Species revolutionized science, philosophy, and theology. Darwin’s reasoned, documented arguments carefully advance his theory of natural selection and his assertion that species were not created all at once by a divine hand but started with a few simple forms that mutated and adapted over time. Whether commenting on his own poor health, discussing his experiments to test instinct in bees, or relating a conversation about a South American burrowing rodent, Darwin’s monumental achievement is surprisingly personal and delightfully readable. Its profound ideas remain controversial even today, making it the most influential book in the natural sciences ever written—an important work not just to its time but to the history of humankind. ~ Publisher’s Description
In considering the Origin of Species, it is quite conceivable that a naturalist, reflecting on the mutual affinities of organic beings, on their embryological relations, their geographical distribution, geological succession, and such other facts, might come to the conclusion that each species had not been independently created, but had descended, like varieties, from other species. Nevertheless, such a conclusion, even if well founded, would be unsatisfactory, until it could be shown how the innumerable species inhabiting this world have been modified, so as to acquire that perfection of structure and coadaptation which most justly excites our admiration.
We can never be sure that the opinion we are endeavoring to stifle is a false opinion; and if we were sure, stifling it would be an evil still. First: the opinion which it is attempted to suppress by authority may possibly be true. Those who desire to suppress it, of course deny its truth; but they are not infallible. They have no authority to decide the question for all mankind, and exclude every other person from the means of judging. To refuse a hearing to an opinion, because they are sure that it is false, is to assume that their certainty is the same thing as absolute certainty. All silencing of discussion is an assumption of infallibility…
Though society is not founded on a contract, and though no good purpose is answered by inventing a contract in order to deduce social obligations from it, every one who receives the protection of society owes a return for the benefit, and the fact of living in society renders it indispensable that each should be bound to observe a certain line of conduct towards the rest. This conduct consists, first, in not injuring the interests of one another; or rather certain interests, which, either by express legal provision or by tacit understanding, ought to be considered as rights; and secondly, in each person’s bearing his share (to be fixed on some equitable principle) of the labors and sacrifices incurred for defending the society or its members from injury and molestation. These conditions society is justified in enforcing, at all costs to those who endeavor to withhold fulfilment. Nor is this all that society may do. The acts of an individual may be hurtful to others, or wanting in due consideration for their welfare, without going the length of violating any of their constituted rights. The offender may then be justly punished by opinion, though not by law. As soon as any part of a person’s conduct affects prejudicially the interests of others, society has jurisdiction over it, and the question whether the general welfare will or will not be promoted by interfering with it, becomes open to discussion. But there is no room for entertaining any such question when a person’s conduct affects the interests of no persons besides himself, or needs not affect them unless they like (all the persons concerned being of full age, and the ordinary amount of understanding). In all such cases there should be perfect freedom, legal and social, to do the action and stand the consequences.
The number of intermediate varieties, which have formerly existed on the earth, (must) be truly enormous. Why then is not every geological formation and every stratum full of such intermediate links? Geology assuredly does not reveal any such finely graduated organic chain; and this, perhaps, is the most obvious and gravest objection which can be urged against my theory.
If it could be demonstrated that any complex organ existed which could not possibly have been formed by numerous successive slight modifications, my theory would absolutely break down. But I can find out no such case. No doubt many organs exist of which we do not know the transitional grades … We should be extremely cautious in concluding that an organ could not have been formed by transitional gradations of some kind.
The liberty of expressing and publishing opinions may seem to fall under a different principle, since it belongs to that part of the conduct of an individual which concerns other people; but, being almost of as much importance as the liberty of thought itself, and resting in great part on the same reasons, is practically inseparable from it. Secondly, the principle requires liberty of tastes and pursuits; of framing the plan of our life to suit our own character; of doing as we like, subject to such consequences as may follow; without impediment from our fellow-creatures, so long as what we do does not harm them, even though they should think our conduct foolish, perverse, or wrong. Thirdly, from this liberty of each individual, follows the liberty, within the same limits, of combination among individuals; freedom to unite, for any purpose not involving harm to others: the persons combining being supposed to be of full age, and not forced or deceived. No society in which these liberties are not, on the whole, respected, is free, whatever may be its form of government; and none is completely free in which they do not exist absolute and unqualified. The only freedom which deserves the name, is that of pursuing our own good in our own way, so long as we do not attempt to deprive others of theirs, or impede their efforts to obtain it. Each is the proper guardian of his own health, whether bodily, or mental and spiritual. Mankind are greater gainers by suffering each other to live as seems good to themselves, than by compelling each to live as seems good to the rest. Though this doctrine is anything but new, and, to some persons, may have the air of a truism, there is no doctrine which stands more directly opposed to the general tendency of existing opinion and practice. Society has expended fully as much effort in the attempt (according to its lights) to compel people to conform to its notions of personal, as of social excellence.
Somewhat it seeketh, and what that is directly it knoweth not, yet very intentive desire thereof doth so incite it, that all other know delights and pleasures are laid aside, they give place to the search of this but only suspected desire. If the soul of man did serve only to give him being in this life, then things appertaining unto this life would content him, as we see they do other creatures; which creatures enjoying what they live by seek no further, but in this contentation do shew a kind of acknowledgment that there is no higher good which doth any way telling unto them. With us it is otherwise. For although the beauties, riches, honors, sciences, virtues, and perfection of all men living, were in the present possession of one; yet somewhat beyond and above all this there would still be sought and earnestly thirsted for. So that Nature even in the life doth plainly claim and call for a more divine perfection than either of these two that have been mentioned.
The prima facie evidence for a God may not be enough to decide the question; but it should at least decide man to entertain the question. To think upon how slight a variation either in man or in external nature, the whole difference between physical enjoyment and the most acute and most appalling of physical agony may turn; to think how delicate the balance is, and yet how surely and steadfastly it is maintained, so as that the vast majority of creatures are not only upheld in comfort but often may be seen disporting themselves in the redundance of gaiety; to think of the pleasurable sensations wherewith every hour is enlivened, and how much the most frequent and familiar occasions of life are mixed up with happiness; to think of the food, and the recreation, and the study, and the society, and the business, each having an appropriate relish of its own, so as in fact to season with enjoyment the great bulk of our existence in the world; to think that, instead of living in the midst of grievous and incessant annoyance to all our faculties, we should have awoke upon a world that so harmonized with the various senses of man, and both gave forth such music to his ear, and to his eye such manifold loveliness; to think of all these palpable and most precious adaptations, and yet to care not, whether in this wide universe there exists a being who has had any hand in them; to riot and regale oneself to the uttermost in the midst of all this profusion, and yet to send not one wishful inquiry after that Benevolence which for aught we know may have laid it at our feet — this, however shaded from our view the object of the question may be, is, from its very commencement, a clear outrage against its ethical proprieties. If that veil of dim transparency, which hides the Deity from our immediate perceptions, were lifted up; and we should then spurn from us the manifested God — this were direct and glaring impiety. But anterior to the lifting of that veil, there may be impiety. It is impiety to be so immersed as we are, in the busy objects and gratifications of life; and yet to care not whether there be a great and a good spirit by whose kindness it is that life is upholden. It needs not that this great spirit should reveal Himself in characters that force our attention to Him, ere the guilt of our impiety has begun. But ours is the guilt of impiety, in not lifting our attention towards God, in not seeking after Him if haply we may find Him.
