It is reasonable to assume that spatial practice, representations of space and representational spaces contribute in different ways to the production of space according to their qualities and attributes, according to the society or mode of production in question, and according to the historical period. Relations between the three moments of the perceived, the conceived and the lived are never either simple or stable, nor are they ‘positive’ in the sense in which this term might be opposed to ‘negative’, to the indecipherable, the unsaid, the prohibited, or the unconscious. Are these moments and their interconnections in fact conscious? Yes — but at the same time they are disregarded or misconstrued. Can they be described as ‘unconscious’? Yes again, because they are generally unknown, and because analysis is able – though not always without error — to rescue them from obscurity. The fact is, however, that these relationships have always had to be given utterance, which is not the same thing as being known – even ‘unconsciously’.
