Perhaps we should have sorted out the definition of "intelligence" we all can agree on first.
This is a very good idea. I would say the definition of intelligence is the ability to apply existing knowledge to new situations and to be able to acquire new knowledge.
Is just giving a definition enough though? We can obviously use that definition to show that computers as we know them are not intelligent. While they can be made to look like they are learning, this is purely as a result of clever programming, using tools such as conditionals and lookup tables. But what about us? While we may feel that we are not programmed and that we really are learning from our experiences, we don't know enough about how the brain works to definitively say that any decisions we make are not just a result of predetermined arrangements of neurons.
