I’ve heard in discussions about abortion that a “person” (something which is morally valuable) is a being who has a rational nature. I’ve also heard that the threshold which divides us from animals is our rationality, our intellect and will.
But I’ve also heard that being and goodness are really the same thing because everything which God made is good. We can also perceive intelligence in some animals and think there are right and wrong ways to treat them even when they lack it.
So I’m not sure what to make of these views. Is a person a rational being or are all things good or are these views compatible? If the former is true, then why do we do we believe that God created everything good? If the latter is true, then why do we say a person is a “rational being”?
