THE in is quite an accepted popular conception without any definite proof of its existence. It is popularly taken for granted that all normal a strong for motherhood. Leta S. Hollingsworth, in an early issue of The American Journal of Sociology, had this statement to make regarding the instinct: There is, to be sure, a strong and fervid insistence on the 'maternal instinct,' which is popularly supposed to characterize all equally, and to furnish them with an all-consuming for parenthood regardless of all personal pain, sacrifice, and disadvantage involved....'') The thesis of this paper is based upon another conclusion from the same Hollingsworth article cited below: There is no verifiable evidence to show that a maternal instinct exists in of such all-consuming strength and fervor as to impel them voluntarily to seek the pain, danger, and exacting labor involved in maintaining a high birth rate. Data to substantiate this thesis were obtained from an unselected group of 183 college students. Schedules were prepared containing reasons for desiring or for not desiring and containing reasons for desiring or for not desiring children. The data were grouped under urban and rural in order to be able to determine if the attitudes of the college of the urban and of the rural areas differed to any great degree regarding and motherhood. The data on desired were classified on the basis of strong desire, undecided, and no desire. For the classification of strong desire, the plus sign (+) is used in the tables; the undecided are indicated by the word untdecided; the no are indicated by the negative sign (-). The basis for determining the strong was from such reasons checked on the schedules as desire for companionship, desire for economic security, and desire for moral security. The undecided were based on such checks as too young to think seriously about and have not thought about it. The no classification was determined by the checks of such reasons as marriage interferes with a career, women can't be independent in marriage, and may be made unhappy by cruelty, infidelity, or by desertion. Only three indicated having no for and these wanted to pursue a career in preference to marriage. The data on attitudes toward motherhood were classified by the plus sign (+) indicating an intense based upon such checked reasons as love children, want experience of motherhood, and religious duty. The plusor-minus sign (i) classifies the data indicating hat are desired as a bond of union in or as a means of security in old age or for These data were labelled plus-orminus because the assumption is taken that if the belief becomes intensely strong that are essential as a bond in the marital union, or that assures the will become strong for motherhood. On the other hand, if this belief is weakened, the will become negative for motherhood. The reasons determining this classification are, children will hold husband and wife together, children will keep interest in the home, children are useful to take care of a parent in old age, and childbirth is essential to a woman's health. The negative sign (-) indicates these schedules checked as do not like children, afraid to risk due to chance of impairing health, and childbirth interferes with occupation. Those undecided were checked under the word undecided. In making an analysis of the data obtained from the 183 college women, it is found that both urban and rural college show the same attitudes toward marriage. Of the 115 urban college women, 113, or 98 percent, registered a definite to become married. The same was found to be true of the 68 rural college women. The schedules showed that 67, or 98 percent had a positive attitude toward marriage.
