Human beings are animals.
As such they have a specific anatomy and physiology, and it seems reasonable to suppose that this results in all members of the species having certain needs, capacities and behavioural dispositions, often referred to as 'human nature'. This is the traditional concern of the natural sciences of biology and psychology. But human beings are also persons or social beings. From this perspective, human beings are traditionally studied by those disciplines that comprise the humanities and social sciences. It is this question that serves to distinguish Human Sciences at Sussex from more orthodox programmes in the biological, psychological or social sciences.
