This text summarises the differences in architecture and proposes, unlike in other art forms, that architecture has a mainstream which has consistency in it, yet is also ever changing. The term 'modern architecture' is becoming suspect and obsolete. Visual art is inevitably involved with social evolution. It discusses utilitarian and creative architecture. Boyd proposes architecture is between science and art, and that architecture by itself means the architecture of this age.Typewritten, quarto, 11 pages (Note: Mentions the 1960s, possibly implying it was written late 1960s-1970/1971)modern architecture, social evolution, utilitarian architecture, creative architecture, mcluhan era, glutternberg era, henry russell hitchcock, paul rudolph, philip johnson, kenzo tange, archigram, sydney opera house, reston, robin boyd, manuscript
