even constitutes the nature of man. In conflict with it no motive is so strong that it would be certain of victory. It is so pre-eminently the chief concern that no other pleasures make up for the deprivation of its satisfaction; and, moreover, for its sake both brute and man undertake every danger and every conflict. A very naive expression of this disposition is the well-known inscription on the door of the fornix at Pompeii, decorated with the phallus: "Heic habitat felicitas:" this was for those going in naïve, for those coming out ironical, and in itself humorous. On the other hand, the excessive power of the sexual passion is seriously and worthily expressed in the inscription which (according to Theon of Smyrna, De Musica, c. 47), Osiris had placed upon the column he erected to the eternal gods: "To Eros, the spirit, the heaven, the sun, the moon, the earth, the night, the day, and the father of all that is and that shall be;" also in the beautiful apostrophe with which Lucretius begins his work:
"Æneadum genetrix, hominum divomque voluptas,
Alma Venus cet."
To all this corresponds the important rôle which the relation of the sexes plays in the world of men, where it is really the invisible central point of all action and conduct, and peeps out everywhere in spite of all veils thrown over it. It is the cause of war and the end of peace, the basis of what is serious, and the aim of the jest, the inexhaustible source of wit, the key to all allusions, and the meaning of all mysterious hints, of all unspoken offers and all stolen glances, the daily meditation of the young, and often also of the old, the hourly thought of the unchaste, and even against their will the constantly recurring imagination of the chaste, the ever ready material of a joke, just because the profoundest seriousness lies at its foundation. It is, however, the piquant element and the joke of life that the chief concern of all men is secretly pursued and ostensibly ignored
