Section IX

The final cause of the difference between the passions belonging to Self-Preservation and those which regard the society of the sexes.

The final cause of the difference in character between the passions which regard self-preservation, and those which are directed to the multiplication¹ of the species, will illustrate² the foregoing remarks yet further; and it is, I imagine, worthy³ of observation even upon its own account. As the performance of our duties of every kind depends upon life, and the performing them with vigor⁴ and efficacy depends upon health, we are very strongly affected⁵ with whatever threatens the destruction of either: but as we were not made to acquiesce⁶ in life and health, the simple enjoyment⁷ of them is not attended with any real pleasure, lest, satisfied with that, we should give ourselves over to indolence and inaction. On the other hand, the generation of mankind is a great purpose, and it is requisite⁸ that men should be animated⁹ to the pursuit of it by some great incentive¹⁰. It is therefore attended with a very high pleasure; but as it is by no means designed to be our constant business, it is not fit that the absence of this pleasure should be attended with any considerable pain. The difference between men and brutes¹¹, in this point, seems to be remarkable¹². Men are at all times pretty equally disposed to the pleasures of love, because they are to be guided by reason in the time and manner of indulging them. Had any great pain arisen from the want of this satisfaction, reason, I am afraid, would find great difficulties in the performance of its office. But brutes that obey laws, in the execution of which their own reason has but little share, have their stated seasons; at such times it is not improbable that the sensation from the want is very troublesome, because the end must be then answered, or be missed in many, perhaps forever; as the inclination¹³ returns only with its season.
