Absence of Evidence, or Evidence of Absence?
A paper on Animal Consciousness

Consciousness is a difficult term to grasp; so much so, that many scientists will not even attempt to define the term, much less search for it's evidence. Most however, do agree that consciousness must include certain aspects; specifically cognition, self-awareness, memory, and abstract thought.
Lesley J. Rogers describes consciousness as, "related to awareness, intelligence, and complex cognition, as well as language. Consciousness may be manifested in self-awareness, awareness of others, intentional behavior, including intentional communication, deception of others, and in the ability to make mental and symbolic representations (13)."
There is no question that humans carry these attributes, but what about animals? Some philosophers, including Descartes, claimed that while humans are conscious, animals are like machines, with no thought process or sentience. Others claim that animals are very capable of consciousness, and that we just have not had the capabilities to test the aspects of it through the scientific method. As Donald R. Griffin expressed:
Conscious thinking may well be a core function of central nervous systems. For conscious animals enjoy the advantage of being able to think about alternative actions and select behavior they believe will get them what they want or help them avoid what they dislike or fear. Of course human consciousness is astronomically more complex and versatile than any conceivable animal thinking, but the basic question addressedÂ…is whether the difference is qualitative and absolute, or whether animals are conscious even though the content of their consciousness is undoubtedly limited and very likely quite different of ours.
