As to voice, which depends on the muscles of respiration, and more immediately on those of the mouth and throat, as general strength does on the muscles of the whole body, both merely affording expressions of the mind, the influence of the sexual union upon it is prodigious. How entirely it is altered by the removal of the testes in eunuchs is known to every one: in corresponding proportion, is it altered by every act of the generative organs, but especially by sexual indulgence during puberty. The horrible voice of early libertines and prostitutes presents an alarming example of this. To those who value voice in conversation, in the delightful and humanizing exercise of music, or in the grander efforts of public speaking, nothing more need be said. As to health, the less we are prodigal of life, the longer we preserve it. Every one capable of observing may see that the stag loses his horns and his hair after procreation; that birds fall into moulting and sadness; and that male insects even perish after this effort, as if they yielded their individual life to their progeny. Indeed, everything perishes so much the more readily, as it has thus transmitted life to its descendants, or has cast it away in vain pleasures. In mankind, as in other animals, to procreate is in effect to die to one's self, and to leave one's life to posterity; especially, if this takes place in early life. It is then that man becomes bald and bent; and that the charms of woman fade. Even in advanced age, epicures are so well aware of this, that they are known to abstain from amorous excess, as the acknowledged cause of premature death. In relation to mind--as the generative power is the source of several characteristics of genius, the exhaustion of that power at an early age must take away these characteristics. Genius as surely languishes and is extinguished amid early sexual indulgence, as do the faculties of voice and locomotion, which are merely its signs and expressions. It is thus with all our faculties, locomotive, vital, mental, at an early age. They are strengthened by all that they do not dissipate; and that which their organs too abundantly dispense is not only taken immediately from their own power, and mediately from that of the other organs, but it ensures the permanent debility of the whole. It is true that the strong passions which are modified or characterized by the sexual impulse, excite the imagination and impel the mind to sublime exertions; but the sole means of either obtaining or preserving such impulsion is, to shun the indulgence of pleasure in early life, and its waste at later periods.
