"Nature hath made men so equal in the faculties of body and mind, as that though there be found one man sometimes manifestly stronger in body, or of quicker mind than another, yet when all is reckoned together, the difference between man and man is not so considerable as that one man can thereupon claim to himself any benefit to which another may not pretend as well as he."

You will see the mercy of God toward His creatures, how He has provided that which is required, in proper proportions, and treated all individual beings of the same species with perfect equality. ...for it is an act of great and perfect goodness that He gave us existence; and the creation of the controlling faculty in animals is a proof of His mercy towards them, as has been shown by us.
