Welfare There is a closer tie than is commonly supposed between the improvement of the soul and the amelioration of what belongs to the body.

Man may leave these two things apart, and consider each of them alternately; but he cannot sever them entirely without at last losing sight of one and of the other.

The beasts have the same senses as ourselves, and very nearly the same appetites.

We have no sensual passions which are not common to our race and theirs, and which are not to be found, at least in the germ, in a dog as well as in a man.

Whence is it then that the animals can only provide for their first and lowest wants, whereas we can infinitely vary and endlessly increase our enjoyments?
We are superior to the beasts in this, that we use our souls to find out those material benefits to which they are only led by instinct.
