"If psychologists are asked what the business of psychology is they generally make some such answer as follows if they belong to the empirical school: that this science has to investigate the facts of consciousness its combinations and relations so that it may ultimately discover the laws which govern these relations and combinations. Now although this definition seems quite perfect it is really to some extent a vicious circle. For if we ask further what is this consciousness which psychology investigates? the answer will be "It consists of the sum total of facts of which we are conscious." In spite of this our definition is the simplest and therefore for the present it will be well for us to keep to it. All objects of experience have this peculiarity namely that we cannot really define them but only point to them and if they are of a complex nature analyse them into their separate qualities. Such an analysis we call a description. We will therefore best be able to answer more accurately the question as to the nature of psychology by describing as exactly as possible all the separate qualities of that consciousness the content of which psychological investigation has to deal with."
