Animals which excel in swiftness are commonly defective in force.

Those which possess both are either imperfect in some of their senses, or are oppressed with the most craving wants.

The human species, whose chief excellency is reason and sagacity, is of all others the most necessitous, and the most deficient in bodily advantages; without clothes, without arms, without food, without lodging, without any convenience of life, except what they owe to their own skill and industry.

In short, nature seems to have formed an exact calculation of the necessities of her creatures; and, like a rigid master, has afforded them little more powers or endowments than what are strictly sufficient to supply those necessities.

An indulgent parent would have bestowed a large stock, in order to guard against accidents, and secure the happiness and welfare of the creature in the most unfortunate concurrence of circumstances.
