Ignasi de Sola-Morales argues that the trajectory of Modern Architecture through the 20th century can no longer be read in one straight line. The presentation of an ideal society no longer exists, "On the contrary, it presents itself to us as a plural, multiform, complex experience in which it is legitimate to cut trajectories that run not only from top to bottom, beginning to end, but also transversely, obliquely, and diagonally. In some sense, it is only by way of approximations of this kind that the diverse, plural experience of the twentieth-century architecture allows us to unstitch and unravel the intrinsic complexity of the modern experience." (Sola-Morales, "Weak Architecture")
For Sola-Morales the reading of history in this manner undermines any idea that there is a ultimate and upright moral outcome, what Nietzsche called "the death of God"; "...that is to say the disappearance of any kind absolute reference that might in some way coordinate or "close" the system of our knowledge and our values at the point at which we articulate these in a global vision of reality." (ibid)
It brings about the end of Illusion, the ground on which we now produce architecture is no longer stable "...contemporary architecture, in conjunction with the other arts, is confronted with the need to build on air, to build in the void."(ibid)
For Sola-Morales the periphery is the place from which all design and life is in this case approached. As a result the aesthetic experience becomes the most substantial, "Art is understood as being a space in which the fatigue of contemporary subject can be salved away"(ibid)
