ENDS.AND MEANS because men wish it to exist; and we know, as a matter of historical fact, that the intensity of that wish has varied from absolute zero to a frenzied maximum. The wish for war in the contemporary world is widespread and of high intensity. But our wills are to some extent free; we can wish otherwise than we actually do. It is enormously difficult for us to change our wishes in this matter; but the enormously difficult is not the impossible. We must be grateful for even the smallest crumbs of comfort. II. Causes of War War exists because people wish it to exist. They wish it to exist for a variety of reasons. (i) Many people like war because they find their peace- time occupations either positively humiliating and frustra- ting, or just negatively boring. In their studies on suicide Durkheim and, more recently, Halbwachs have shown that the suicide rate among non-combatants tends to fall during war-time to about two-thirds of its normal figure. This decline must be put down to the following causes: to the simplification of life during war-time (it is in complex and highly developed societies that the suicide rate is highest); to the intensification of nationalist sentiment to a point where most individuals are living in a state of chronic enthusiasm; to the fact that life during war-time takes on significance and purposefulness, so that even the most intrinsically boring job is ennobled as * war-work'; to the artificial prosperity induced, at any rate for a time, by the expansion of war industies; to the increased sexual freedom • which is always claimed by societies, all or some of whose members live under the menace of sudden death.
