The result is that we are not only dominated by the suggestion of our visions, but we are unable adequately to appreciate and criticise the situations which are presented to us. We instinctively continue to reason, and to reason clearly and logically with the material at our disposal, but our reasoning is hopelessly absurd. We perceive in dreams, but we do not apperceive; we cannot, that is to say, test and sift the new experience, and co-ordinate it adequately with the whole body of our acquired mental possessions. The phenomena of dreaming furnish a delightful illustration of the fact that reasoning, in its rough form, is only the crudest and most elementary form of intellectual operation, and that the finer forms of thinking involve much more than logic. 'All the thinking in the world,' as Goethe puts it, 'will not lead us to thought.' FOOTNOTES: [Footnote 42: Freud brings together (_Traumdeutung_, pp. 38 _et seq._) some of the different opinions regarding reasoning in dreams.] [Footnote 43: 'Reasoning,' says Binet (_La Psychologie du Raisonnement_, 1886, p. 10), speaking without reference to dreaming, but in words that are exactly applicable to it, 'is an organisation of images determined by the properties of the images alone; it suffices for the images to be put in presence and they become organised; reason follows with the certainty of a reflex.'] [Footnote 44: H. R. Marshall, _Instinct and Reason;_ _ib._ 'Reason a Mode of Instinct,' _Psychological Review_, March 1899.] [Footnote 45: Some of the most methodically absurd examples of dreaming logic cannot be effectively brought forward, as they are so personal that they require much explanation to make them intelligible.] [Footnote 46: Delacroix ('Sur la Structure Logique du Rêve,' _Revue de Metaphysique_, November 1904), in opposition to Leroy and Tobolowska, goes so far as to say that 'the sense of the dream, the interpretation of the image, is given in the image, before the image, if one may say so; we are not concerned with a mere procession of images without internal connection, but are introduced into a pre-established organisation; wholes are decomposed and not separate elements united.' We have to remember that in dream life as in waking life the action is twofold; in either world when our psychic activity is of low intensity we combine external images into a fairly objective picture; when psychic activity is intense external images are subdued and controlled by that activity.]
