of purely subjective conceptions. Apart from this subjective view of Appearance, however, we have all reason to rejoice that the things which environ us are appearances and not steadfast and independent existences; since in that case we should soon perish of hunger, both bodily and mental. (a) _The World of Appearance._ 132.] The Apparent or Phenomenal exists in such a way, that its subsistence is _ipso facto_ thrown into abeyance or suspended and is only one stage in the form itself. The form embraces in it the matter or subsistence as one of its characteristics. In this way the phenomenal has its ground in this (form) as its essence, its reflection-into-self in contrast with its immediacy, but, in so doing, has it only in another aspect of the form. This ground of its is no less phenomenal than itself, and the phenomenon accordingly goes on to an endless mediation of subsistence by means of form, and thus equally by non-subsistence. This endless inter-mediation is at the same time a unity of self-relation; and existence is developed into a totality, into a world of phenomena,--of reflected finitude. (b) _Content and Form._ 133.] Outside one another as the phenomena in this phenomenal world are, they form a totality, and are wholly contained in their self-relatedness. In this way the self-relation of the phenomenon is completely specified, it has the Form in itself: and because it is in this identity, has it as essential subsistence. So it comes about that the form is Content: and in its mature phase is the Law of the Phenomenon. When the form, on the contrary, is not reflected into self, it is equivalent to the negative of the phenomenon, to the non-independent and changeable: and that sort of form is the indifferent or External Form. The essential point to keep in mind about the opposition of Form and Content is that the content is not formless, but has the form in its own self, quite as much as the form is external to it. There is thus a doubling of form. At one time it is reflected into itself; and then is identical with the content. At another time it is not reflected into itself, and then is the external existence, which does not at all affect the content. We are here in presence, implicitly, of the absolute correlation of content and form: viz. their reciprocal revulsion, so that content is nothing but the revulsion of form into content, and form nothing but the revulsion of content into form. This mutual revulsion is one of the most important laws of thought. But it is not explicitly brought out before the Relations of Substance and Causality.
