'We, the representatives at our table, have employed the rational faculty of our minds to look into the source of conjugial love and that of its strength or potency. Having taken an all-round look at the reasons, we have seen and proved that the only source is the fact that everyone as a result of the stimuli and their prodding which lie concealed in the depths of his mind and body finds his eyes leading him to varying lusts, but eventually he concentrates and shapes his mind towards one member of the female sex, until his passion for her grows hot. From this time on his heat develops a series of flames, until it becomes a fire. In that state sexual lust departs and the place of lust is taken by conjugial love. When the young bridegroom is hot with this fire, he is unaware that the strength or potency of that love will ever fade, since he lacks the experience which could teach him about the way its strength declines and love cools off after achieving its delights. The source of conjugial love therefore is from that first ardour which precedes marriage, and this is also the source of its strength or potency. But after the wedding there is a change in his potency, and it increases and decreases in turn. But it still lasts until old age, decreasing and increasing in a constant rhythm, because it is controlled by prudence and the lusts are checked which burst out of the as yet unpurified caverns of the mind. For lust is the forerunner of wisdom. This is our judgment about the source and persistence of marital strength or potency.' This paper was signed with the letter P.
