In What emotions really are and in other papers Griffiths states that in Biology, natural classes ofliving organisms are clades. This assertion is made within the bounds of a new theory of natural classes. In this paper I wiIl consider the arguments employed by Griffiths to support the privileged status of the cladistic classification over other classifications. It is not Griffith's theory of natural classes what will be discussed, but his ability to offer a solution to the particular issue ofwhich classification system of organisms should be used in Biology.
