I am assuming, npetreley, you mean that philosophically, rather than insultorally
And that is how i will answer that question... Which is important because it requires a definition of what intelligence is.
I think there can be many levels/degrees/facets of intelligence, for instance; I think the ability to learn is very important, as is understanding cause and effect. Although one does not have to realize what the abstract term "cause and effect" mean, but only to be aware, like a dog, that if it chews up its master's shoe, it will get a swat.
I also think that that higher forms of intelligence require self-awareness, the ability to think abstractly (in mature and healthy specimens of a species).
There are many more attributes that I attach to intelligence, and I think I fit the bill for all of them, to one degree or another. But is intelligence related to memory?
And right back at ya, why do you think you are intelligent?
