An Essay on the Principle of Population

The obscurity that involves all metaphysical subjects appears to me, in the same manner, peculiarly calculated to add to that class of excitements which arise from the thirst of knowledge. It is probable that man, while on earth, will never be able to attain complete satisfaction on these subjects; but this is by no means a reason that he should not engage in them. The darkness that surrounds these interesting topics of human curiosity may be intended to furnish endless motives to intellectual activity and exertion. The constant effort to dispel this darkness, even if it fail of success, invigorates and improves the thinking faculty. If the subjects of human inquiry were once exhausted, mind would probably stagnate; but the infinitely diversified forms and operations of nature, together with the endless food for speculation which metaphysical subjects offer, prevent the possibility that such a period should ever arrive.

It is by no means one of the wisest sayings of Solomon that 'there is no new thing under the sun.' On the contrary, it is probable that were the present system to continue for millions of years, continual additions would be making to the mass of human knowledge, and yet, perhaps, it may be a matter of doubt whether what may be called the capacity of mind be in any marked and decided manner increasing. A Socrates, a Plato, or an Aristotle, however confessedly inferior in knowledge to the philosophers of the present day, do not appear to have been much below them in intellectual capacity. Intellect rises from a speck, continues in vigour only for a certain period, and will not perhaps admit while on earth of above a certain number of impressions. These impressions may, indeed, be infinitely modified, and from these various modifications, added probably to a difference in the susceptibility of the original germs, arise the endless diversity of character that we see in the world; but reason and experience seem both to assure us that the capacity of individual minds does not increase in proportion to the mass of existing knowledge. (It is probable that no two grains of wheat are exactly alike. Soil undoubtedly makes the principal difference in the blades that spring up, but probably not all. It seems natural to suppose some sort of difference in the original germs that are afterwards awakened into thought, and the extraordinary difference of susceptibility in very young children seems to confirm the supposition.)

The finest minds seem to be formed rather by efforts at original thinking, by endeavours to form new combinations, and to discover new truths, than by passively receiving the impressions of other men's ideas. Could we suppose the period arrived, when there was not further hope of future discoveries, and the only employment of mind was to acquire pre-existing knowledge, without any efforts to form new and original combinations, though the mass of human knowledge were a thousand times greater than it is at present, yet it is evident that one of the noblest stimulants to mental exertion would have ceased; the finest feature of intellect would be lost; everything allied to genius would be at an end; and it appears to be impossible, that, under such circumstances, any individuals could possess the same intellectual energies as were possessed by a Locke, a Newton, or a Shakespeare, or even by a Socrates, a Plato, an Aristotle or a Homer.

If a revelation from heaven of which no person could feel the smallest doubt were to dispel the mists that now hang over metaphysical subjects, were to explain the nature and structure of mind, the affections and essences of all substances, the mode in which the Supreme Being operates in the works of the creation, and the whole plan and scheme of the Universe, such an accession of knowledge so obtained, instead of giving additional vigour and activity to the human mind, would in all probability tend to repress future exertion and to damp the soaring wings of intellect.

For this reason I have never considered the doubts and difficulties that involve some parts of the sacred writings as any ardent against their divine original. The Supreme Being might, undoubtedly, have accompanied his revelations to man by such a succession of miracles, and of such a nature, as would have produced universal overpowering conviction and have put an end at once to all hesitation and discussion. But weak as our reason is to comprehend the plans of the great Creator, it is yet sufficiently strong to see the most striking objections to such a revelation. From the little we know of the structure of the human understanding, we must be convinced that an overpowering conviction of this kind, instead of tending to the improvement and moral amelioration of man, would act like the touch of a torpedo on all intellectual exertion and would almost put an end to the existence of virtue. If the scriptural denunciations of eternal punishment were brought home with the same certainty to every man's mind as that the night will follow the day, this one vast and gloomy idea would take such full possession of the human faculties as to leave no room for any other conceptions, the external actions of men would be all nearly alike, virtuous conduct would be no indication of virtuous disposition, vice and virtue would be blended together in one common mass, and though the all-seeing eye of God might distinguish them they must necessarily make the same impressions on man, who can judge only from external appearances. Under such a dispensation, it is difficult to conceive how human beings could be formed to a detestation of moral evil, and a love and admiration of God, and of moral excellence.

Our ideas of virtue and vice are not, perhaps, very accurate and well-defined; but few, I think, would call an action really virtuous which was performed simply and solely from the dread of a very great punishment or the expectation of a very great reward. The fear of the Lord is very justly said to be the beginning of wisdom, but the end of wisdom is the love of the Lord and the admiration of moral good. The denunciations of future punishment contained in the scriptures seem to be well calculated to arrest the progress of the vicious and awaken the attention of the careless, but we see from repeated experience that they are not accompanied with evidence of such a nature as to overpower the human will and to make men lead virtuous lives with vicious dispositions, merely from a dread of hereafter. A genuine faith, by which I mean a faith that shews itself in it the virtues of a truly Christian life, may generally be considered as an indication of an amiable and virtuous disposition, operated upon more by love than by pure unmixed fear.

When we reflect on the temptations to which man must necessarily be exposed in this world, from the structure of his frame, and the operation of the laws of nature, and the consequent moral certainty that many vessels will come out of this mighty creative furnace in wrong shapes, it is perfectly impossible to conceive that any of these creatures of God's hand can be condemned to eternal suffering. Could we once admit such an idea, it our natural conceptions of goodness and justice would be completely overthrown, and we could no longer look up to God as a merciful and righteous Being. But the doctrine of life and Mortality which was brought to light by the gospel, the doctrine that the end of righteousness is everlasting life, but that the wages of sin are death, is in every respect just and merciful, and worthy of the great Creator. Nothing can appear more consonant to our reason than that those beings which come out of the creative process of the world in lovely and beautiful forms should be crowned with immortality, while those which come out misshapen, those whose minds are not suited to a purer and happier state of existence, should perish and be condemned to mix again with their original clay. Eternal condemnation of this kind may be considered as a species of eternal punishment, and it is not wonderful that it should be represented, sometimes, under images of suffering. But life and death, salvation and destruction, are more frequently opposed to each other in the New Testament than happiness and misery. The Supreme Being would appear to us in a very different view if we were to consider him as pursuing the creatures that had offended him with eternal hate and torture, instead of merely condemning to their original insensibility those beings that, by the operation of general laws, had not been formed with qualities suited to a purer state of happiness.

Life is, generally speaking, a blessing independent of a future state. It is a gift which the vicious would not always be ready to throw away, even if they had no fear of death. The partial pain, therefore, that is inflicted by the supreme Creator, while he is forming numberless beings to a capacity of the highest enjoyments, is but as the dust of the balance in comparison of the happiness that is communicated, and we have every reason to think that there is no more evil in the world than what is absolutely necessary as one of the ingredients in the mighty process.

The striking necessity of general laws for the formation of intellect will not in any respect be contradicted by one or two exceptions, and these evidently not intended for partial purposes, but calculated to operate upon a great part of mankind, and through many ages. Upon the idea that I have given of the formation of mind, the infringement of the general law of nature, by a divine revelation, will appear in the light of the immediate hand of God mixing new ingredients in the mighty mass, suited to the particular state of the process, and calculated to give rise to a new and powerful train of impressions, tending to purify, exalt, and improve the human mind. The miracles that accompanied these revelations when they had once excited the attention of mankind, and rendered it a matter of most interesting discussion, whether the doctrine was from God or man, had performed their part, had answered the purpose of the Creator, and these communications of the divine will were afterwards left to make their way by their own intrinsic excellence; and, by operating as moral motives, gradually to influence and improve, and not to overpower and stagnate the faculties of man.

It would be, undoubtedly, presumptuous to say that the Supreme Being could not possibly have effected his purpose in any other way than that which he has chosen, but as the revelation of the divine will which we possess is attended with some doubts and difficulties, and as our reason points out to us the strongest objections to a revelation which would force immediate, implicit, universal belief, we have surely just cause to think that these doubts and difficulties are no argument against the divine origin of the scriptures, and that the species of evidence which they possess is best suited to the improvement of the human faculties and the moral amelioration of mankind.

The idea that the impressions and excitements of this world are the instruments with which the Supreme Being forms matter into mind, and that the necessity of constant exertion to avoid evil and to pursue good is the principal spring of these impressions and excitements, seems to smooth many of the difficulties that occur in a contemplation of human life, and appears to me to give a satisfactory reason for the existence of natural and moral evil, and, consequently, for that part of both, and it certainly is not a very small part, which arises from the principle of population. But, though, upon this supposition, it seems highly improbable that evil should ever be removed from the world; yet it is evident that this impression would not answer the apparent purpose of the Creator; it would not act so powerfully as an excitement to exertion, if the quantity of it did not diminish or increase with the activity or the indolence of man. The continual variations in the weight and in the distribution of this pressure keep alive a constant expectation of throwing it off.

"Hope springs eternal in the Human breast,Man never is, but always to be blest."

Evil exists in the world not to create despair but activity. We are not patiently to submit to it, but to exert ourselves to avoid it. It is not only the interest but the duty of every individual to use his utmost efforts to remove evil from himself and from as large a circle as he can influence, and the more he exercises himself in this duty, the more wisely he directs his efforts, and the more successful these efforts are; the more he will probably improve and exalt his own mind, and the more completely does he appear to fulfil the will of his Creator.
