Before one can answer this question, one must define what is meant by thought.Thought can be defined in several ways: is it philosophical rumination or the processing of perceptions of the natural world? Because we are still trying to translate animal communication into human language, it is difficult to provide definitive proof ofphilosophical thought processes. Current studies by animal behaviorists indicate that animals that have a varied social life (such as chimpanzees) perceive the world inways similar to humans. However, since we do not share a common verbal language with animals, it is impossible to know what they are thinking.
