The four essays that compose this book depict infrequent orbits around the relationship between architecture and the bodies that inhabit it, accounting for the resistance presented by corporeity to disappear from architectonic space. From the start of modernity the body has seen its carnality substituted by a whole series of systems or devices: geometrical, functional, perceptive or emotional, amongst many others. Space has suffered a similar instrumentalising which, in a terrorised scenario facing substances and more prone to adjectivation –always safer than nominalism, has been adjectivated, like the body, for not belonging to any specific field of knowledge and belonging to all of them at the same time. In the first case we have a dynamic system of axis, in the second an obedient engine, in the third an unexpected sensor and in the fourth a compound of affections. None of these models result in a satisfactory portrait because they are incomplete, but all together perhaps they can provide a gradual approach to these intimately connected complex substances. As any other path, this one can also be done in the opposite direction, but doing it does not imply going back to the origin point in the same state in which it started.
