the balance (out of stock)

"Anything that exists in Nature which we judge to be evil or able to hinder us from existing and enjoying a rational life, we are allowed to remove from us in that way which seems the safest; and whatever, on the other hand, we judge to be good or to be profitable for the preservation of our being or the enjoyment of a rational life, we are permitted to take for our use and use in any way we may think proper; and absolutely, every one is allowed by the highest right of Nature to do that which he believes contributes to his own profit".
