I can not answer for the author of this post, but this comment is similar
to one which I would make regarding this issue, so here is what I would
mean by it. The answer to whether or not animals are conscious is
obviously yes because humans are animals. But someone could claim that
this does not imply that all animals are conscious. However, what you
actually know is only that YOU are conscious. You can not know for
certain whether or not any other human being is conscious. But we assume
that they are. We should be consistent. The evidence that other species
are conscious is of the exact same quality as evidence that other human
beings are conscious. To be consistent you should either believe that
our own species and other species are both conscious, or that humans
(other than yourself) and other species are both unconscious. The second
alternative is clearly unacceptable.
For those of you who are about to reply by listing all the features
regarding humans which you think provide evidence of consciousness and do
not exist in other species, please first read the other (somewhat lengthy)
post which I just made.
Regarding this whole silly mirror thing, it is a mistake to assume that
consciousness necessarily implies the ability to recognize your
reflection in a mirror. I would agree that a being which recognizes its
reflection in a mirror is probably conscious, but it is incorrect to assume
that a being is not conscious because it does not recognize its reflection. A
severely mentally retarded human might not recognize his reflection, but
this does not mean that he is not conscious.
