Would anyone care to show eveidence for the lack of
self-awareness in other animals or of their inability to reason
about the consequences of their actions ?
Schraf::
Uh, sure, I can show that. It's the "dot on the forehead" test.
Take an animal, put a dot on their forehead, and have them look in a mirror. The ONLY animals that reach to
their foreheads instead of the mirror are chimps and humans.
Peter::
Human babies fail that test until they are several months old, and
primitive cultures when shown photographs of themselves fail to
recognise that the image is of them.
That test shows nothing about self awareness, only of an inability
to comprehend mirrors (or at least the result is inconclusive
either way).
(Western at least) humans are inundated from an early age
with images of themselves, and are TAUGHT that the image is
themself.

Schraf::
"Learning" about the consequences of actions (cause and effect) is a lot different from "reasoning" (using logic) about the consequences of actions.
What about creatures like squirrels and crows, who 'figure out'
how to solve succesively difficult problems in obtaining food
rewards. Crows are particularly good at it, and abilities
learned by parents have been seen to be passed on to offspring.
Even better are the monkeys who wash their sweet potatoes
and use the sea to separate grain from sand. One monkey
worked out how to do it, and others copied. How did the
first monkey find this out ? By accident perhaps, but then
why repeat the process another time if there is not some
form of reasoning like 'It worked last time I'll try again' ?

Peter::
How would you be able to hunt in organised groups without some
planning ability and communication system ? Have you ever
watched lionesses hunt (on TV anyhow) ... can you really believe
that such co-operation could be instinctive ?? A hunt
is an incredibly dynamic activity after all.
Schraf::
Yes, I really can accept that much of that cooperation could be instinctive, the same way that I accept that
birds build nests without being taught, and a housecat who has never hunted a live animal in its life will still
stalk and kill a toy mouse exactly like a feral cat does.
My cat was taken away from it's mother very young ... and
it DOES NOT stalk at all. Sure it'll chase shiny/moving objects,
but it doesn't stalk, because it has never been shown how.
Hunting is an ACQUIRED skill, not an instinctive activity.
quote:
Schraf::
Animals, such as lions, hunting in groups are using both instinct and learned behaviors, but not reason as I have defined it.
I cannot imagine how an ambush (which lionesses
employ with great success) can be imprinted from instinct, nor
co-ordinated without some rudimentary communication technique.
I've seen film of lionesses hunting where the lionesses (two of
them) walk side by side, heads close together, then one sneaks
around the edge of a heard and the other waits till it is in
position before startling the heard toward the now hidden
hunting partner. That seems pretty complicated pattern to be just
instinct ... and if it's learned, how did they learn it in the first
place ?

I think I meant herd
