The relationship between these four attitudes—objectivity, immediacy, subjectivity, and reflexion—is worth consideration. At first sight it might seem that there is no difference between immediacy and subjectivity, or between objectivity and reflexion. Subjectivity and objectivity, certainly, are opposed; and so are immediacy and reflexion. But immediacy (which is naive acceptance of whatever is presented) is compatible with objectivity, as we see from Thomas Huxley's advice to the scientist: 'Sit down before fact as a little child'—; and reflexion is compatible with subjectivity (for subjectivity is 'being oneself', and reflexion, being 'self awareness', is within subjectivity). In emotional excitement objectivity and reflexion alike tend to vanish, and subjectivity then approximates to immediacy. It is this that gives subjectivity its bad name; for few people know of any subjectivity beyond emotional immediacy. Their escape from emotion is towards objectivity, in the form of distractions, rather than towards reflexion, which is the more difficult way of self control. Goethe once described the advice 'Know Thyself' (inscribed in the temple of Apollo at Delphi) as 'a singular requisition with which no man complies, or indeed ever will comply: man is by all his senses and efforts directed to externals—to the world about him'.
