This paper details how the hypothesis was reached for a research project regarding the study of architectural composition. The answers to two questions are also addressed: what can be understood by architectural composition, and how can architectural composition be learnt? The answers to these research questions have been previously contemplated by three peripheral questions regarding number, level of autonomy, and the necessity or eventuality of what is learnt from composition architecture. Through answering these peripheral questions, how the hypothesis was reached becomes clear, according to the concept of freedom of expression. Taken from an aesthetic point of view, this is juxtaposed with the understanding of the study of architectural composition from a psychological viewpoint. A philosophical description of language is developed, the purpose of which is to supplement the individual’s point of view with that of the group.
