It is my conviction that all animals, including invertebrates, possess a mind. This conviction is not based on scientific evidence. We are unable to observe the mind directly. According to the principle of parsimony, I assume that body and mind are two aspects of the same. This assumption predicts that it will always be possible to find a bodily explanation, implying that it will never be possible to perform an experiment that proves that a mind is present in any animal species, including human beings. As a result, it will never be possible to prove scientifically that my conviction that all animals possess a mind is correct or wrong.
