  Humans have always constructed spaces, through Mythos and Logos, as part of
an aspiration to capture the essence of the changing world. This has been a
permanent endeavour since the invention of language. By doing this, in fact,
Humankind started constructing itself: we are beings in constant evolutionary
process in real and imaginary spaces. Our concepts of Space and our
anthropological ideas, specially the fundamental concepts of subject and
subjectivity, are intertwined and intimately connected. We believe that the
great narratives about Humanity, which ultimately define our view of ourselves,
are entangled with those concepts that Cassirer identified as the cornerstones
of culture: space, time, and number. To explore these ideas, the authors wrote
an essay, in 2017, in a book format, in which the fundamental role of real and
imaginary spaces (and especially of their dimensionalities) in the History of
Culture was discussed. This book, titled "O Livro, o Espa\c{c}o e a Natureza:
Ensaio Sobre a Leitura do Mundo, as Muta\c{c}\~oes da Cultura e do Sujeito",
has a preface written by Francisco Antonio Doria. As many of the issues treated
there are among his multiple interests, it was decided to revisit here the
problems of subjectivity and subject's relationship with the dimensionality of
space including the question of the architecture of books and other writing
supports.
