It is well to remember that substance does not necessarily imply either extension or figure. Substantia is simply that which stands under, underlies, supports, or in other words that which is the ground of phenomena. The propagation of mind therefore does not involve any dividing up, or splitting off, as if the mind were a material mass. Flame is propagated, but not by division and subdivision. Professor Ladd is a creatianist, together with Lotze, whom he quotes, but he repudiates the idea that the mind is susceptible of division; see Ladd, Philosophy of Mind, 206, 359-366—“The mind comes from nowhere, for it never was, as mind, in space, is not now in space, and cannot be conceived of as coming and going in space.... Mind is a growth.... Parents do not transmit their minds to their offspring. The child's mind does not exist before it acts. Its activities are its existence.” So we might say that flame has no existence before it acts. Yet it may owe its existence to a preceding flame. The Indian proverb is: “No lotus without a stem.” Hall Caine, in his novel The Manxman, tells us that the Deemster of the Isle of Man had two sons. These two sons were as unlike each other as are the inside and the outside of a bowl. But the bowl was old Deemster himself. Hartley Coleridge inherited his father's imperious desire for stimulants and with it his inability to resist their temptation.
(c) The observed transmission not merely of physical, but of mental and spiritual, characteristics in families and races, and especially the uniformly evil moral tendencies and dispositions which all men possess from their birth, are proof that in soul, as well as in body, we derive our being from our human ancestry.
Galton, in his Hereditary Genius, and Inquiries into Human Faculty, furnishes abundant proof of the transmission of mental and spiritual characteristics from father [pg 496]to son. Illustrations, in the case of families, are the American Adamses, the English Georges, the French Bourbons, the German Bachs. Illustrations, in the case of races, are the Indians, the Negroes, the Chinese, the Jews. Hawthorne represented the introspection and the conscience of Puritan New England. Emerson had a minister among his ancestry, either on the paternal or the maternal side, for eight generations back. Every man is “a chip of the old block.” “A man is an omnibus, in which all his ancestors are seated” (O. W. Holmes). Variation is one of the properties of living things,—the other is transmission. “On a dissecting table, in the membranes of a new-born infant's body, can be seen ‘the drunkard's tinge.’ The blotches on his grand-child's cheeks furnish a mirror to the old debauchee. Heredity is God's visiting of sin to the third and fourth generations.” On heredity and depravity, see Phelps, in Bib. Sac., Apr. 1884:254—“When every molecule in the paternal brain bears the shape of a point of interrogation, it would border on the miraculous if we should find the exclamation-sign of faith in the brain-cells of the child.”
Robert G. Ingersoll said that most great men have great mothers, and that most great women have great fathers. Most of the great are like mountains, with the valley of ancestors on one side and the depression of posterity on the other. Hawthorne's House of the Seven Gables illustrates the principle of heredity. But in his Marble Faun and Transformation, Hawthorne unwisely intimates that sin is a necessity to virtue, a background or condition of good. Dryden, Absalom and Ahithophel, 1:156—“Great wits are sure to madness near allied, And thin partitions do their bounds divide.” Lombroso, The Man of Genius, maintains that genius is a mental disease allied to epileptiform mania or the dementia of cranks. If this were so, we should infer that civilization is the result of insanity, and that, so soon as Napoleons, Dantes and Newtons manifest themselves, they should be confined in Genius Asylums. Robert Browning, Hohenstiel-Schwangau, comes nearer the truth: “A solitary great man's worth the world. God takes the business into his own hands At such time: Who creates the novel flower Contrives to guard and give it breathing-room.... 'Tis the great Gardener grafts the excellence On wildlings, where he will.”
(d) The traducian doctrine embraces and acknowledges the element of truth which gives plausibility to the creatian view. Traducianism, properly defined, admits a divine concurrence throughout the whole development of the human species, and allows, under the guidance of a superintending Providence, special improvements in type at the birth of marked men, similar to those which we may suppose to have occurred in the introduction of new varieties in the animal creation.
Page-Roberts, Oxford University Sermons: “It is no more unjust that man should inherit evil tendencies, than that he should inherit good. To make the former impossible is to make the latter impossible. To object to the law of heredity, is to object to God's ordinance of society, and to say that God should have made men, like the angels, a company, and not a race.” The common moral characteristics of the race can only be accounted for upon the Scriptural view that “that which is born of the flesh is flesh” (John 3:6). Since propagation is a propagation of soul, as well as body, we see that to beget children under improper conditions is a crime, and that fœticide is murder. Haeckel, Evolution of Man, 2:3—“The human embryo passes through the whole course of its development in forty weeks. Each man is really older by this period than is usually assumed. When, for example, a child is said to be nine and a quarter years old, he is really ten years old.” Is this the reason why Hebrews call a child a year old at birth? President Edwards prayed for his children and his children's children to the end of time, and President Woolsey congratulated himself that he was one of the inheritors of those prayers. R. W. Emerson: “How can a man get away from his ancestors?”Men of genius should select their ancestors with great care. When begin the instruction of a child? A hundred years before he is born. A lady whose children were noisy and troublesome said to a Quaker relative that she wished she could get a good Quaker governess for them, to teach them the quiet ways of the Society of Friends. “It would not do them that service,” was the reply; “they should have been rocked in a Quaker cradle, if they were to learn Quakerly ways.”
Galton, Natural Inheritance, 104—“The child inherits partly from his parents, partly from his ancestry. In every population that intermarries freely, when the genealogy of any man is traced far backwards, his ancestry will be found to consist of such varied [pg 497]elements that they are indistinguishable from the sample taken at haphazard from the general population. Galton speaks of the tendency of peculiarities to revert to the general type, and says that a man's brother is twice as nearly related to him as his father is, and nine times as nearly as his cousin. The mean stature of any particular class of men will be the same as that of the race; in other words, it will be mediocre. This tells heavily against the full hereditary transmission of any rare and valuable gift, as only a few of the many children would resemble their parents.” We may add to these thoughts of Galton that Christ himself, as respects his merely human ancestry, was not so much son of Mary, as he was Son of man.
Brooks, Foundations of Zoölogy, 144-167—In an investigated case, “in seven and a half generations the maximum ancestry for one person is 382, or for three persons 1146. The names of 452 of them, or nearly half, are recorded, and these 452 named ancestors are not 452 distinct persons, but only 149, many of them, in the remote generations, being common ancestors of all three in many lines. If the lines of descent from the unrecorded ancestors were interrelated in the same way, as they would surely be in an old and stable community, the total ancestry of these three persons for seven and a half generations would be 378 persons instead of 1146. The descendants of many die out. All the members of a species descend from a few ancestors in a remote generation, and these few are the common ancestors of all. Extinction of family names is very common. We must seek in the modern world and not in the remote past for an explanation of that diversity among individuals which passes under the name of variation. The genealogy of a species is not a tree, but a slender thread of very few strands, a little frayed at the near end, but of immeasurable length. A fringe of loose ends all along the thread may represent the animals which having no descendants are now as if they had never been. Each of the strands at the near end is important as a possible line of union between the thread of the past and that of the distant future.”
Weismann, Heredity, 270, 272, 380, 384, denies Brooks's theory that the male element represents the principle of variation. He finds the cause of variation in the union of elements from the two parents. Each child unites the hereditary tendencies of two parents, and so must be different from either. The third generation is a compromise between four different hereditary tendencies. Brooks finds the cause of variation in sexual reproduction, but he bases his theory upon the transmission of acquired characters. This transmission is denied by Weismann, who says that the male germ-cell does not play a different part from that of the female in the construction of the embryo. Children inherit quite as much from the father as from the mother. Like twins are derived from the same egg-cell. No two germ-cells contain exactly the same combinations of hereditary tendencies. Changes in environment and organism affect posterity, not directly, but only through other changes produced in its germinal matter. Hence efforts to reach high food cannot directly produce the giraffe.
