Generally, I would describe myself as favoring the “credo ut intelligam” approach to things (“I believe in order that I may understand”), but reason is also God’s gift and, used rightly, science reveals truth, as in this recent eSkeptic feature about experimental attempts to teach chimpanzees, etc., various types of sign-language, which shows that, just as many of us have always believed,
Descartes was right after all. Animals do not understand language.
In fiction, I’ll fall for a Bonzo or the signing gorilla in Return to Me as easily as the next person, but in reality, there’s no getting around it: humans are unique. Now if we can just live up to all that implies.
