It is always found that especial conservatism attaches to customs and ideas associated with death; the disinclination to exercise independent thought on a subject so serious leaves the field open for the continuance of ancestral notions and practices. It is therefore natural that the volume of superstition associated with the end of life should only be paralleled by that connected with the marriage relation. A vast number of actions and experiences still pass as the "signs" of approaching departure. As in omens generally, the prevailing principle is usually the effect of association of ideas; the shock to the nerves consequent on the imagination of the occurrence is, in the popular fancy, inseparable from belief in its reality. Hence the general tendency to insist on euphemistic speech, the required abstinence from unpleasant suggestions, the _favete linguis_ of the Roman. In this body of deeds to be avoided, ancient and modern notions are interwoven. One must not pass under a ladder, for a ladder is used in modern executions; one must not carry a spade through the house, for with a spade is dug a grave. More in accordance with fundamentally human ideas, the delicate rose of fall presages the untimely waning of a youthful life. As with all superstition, the sign is not merely the prediction of an event; it is felt that as the avoidance of the omen would be to escape its consequence, so the careless action, in becoming the presage of calamity, is likewise its cause. Here appear natural antinomies of human thought: on the one hand, the sense of the inevitableness of the designated fate; on the other hand, the consciousness of ability by altering conditions to change conclusions. Thus the thoughts and actions of primitive man are inspired by the same contending intellectual forces which in later time appear under the guise of warring philosophies.
