“In all of my universe I have seen no law of nature, unchanging and inexorable. This universe presents only changing relationships which are somtimes seen as laws by short-lived awareness. These fleshy sensoria which we call self are ephemera withering in the blaze of infinity, fleetingly aware of temporary conditions which confine our activities and change as our activities change. If you must label the absolute, use its proper name: Temporary.”

“Not only does the universe have its own laws, all of them indifferent to the contradictory dreams and desires of humanity, and in the formulation of which we contribute not one iota, apart, that is, from the words by which we clumsily name them, but everything seems to indicate that it uses these laws for aims and objectives that transcend and always will transcend our understanding.”

“That which has died falls not out of the universe. If it stays here, it also changes here, and is dissolved into its proper parts, which are elements of the universe and of thyself. And these too change, and they murmur not".”

“Unitary urbanism's point of departure is the changeableness of our aspirations and our activities. We know that neither eternal truth nor absolute beauty exist and that, for this reason, ideal form does not exist. Form that is in constant modulation and in agreement with the unceasingly changing aspects of our existence, such as we will produce it. The environment in which we live influences our activity, but reciprocally this environment is a product of our creative activity.”

“The present writer had occasion, some time ago, to call attention to the succession of layers of "laws of nature," each layer containing more general and more encompassing laws than the previous one and its discovery constituting a deeper penetration into the structure of the universe than the layers recognized before. However, the point which is most significant in the present context is that all these laws of nature contain, in even their remotest consequences, only a small part of our knowledge of the inanimate world. All the laws of nature are conditional statements which permit a prediction of some future events on the basis of the knowledge of the present, except that some aspects of the present state of the world, in practice the overwhelming majority of the determinants of the present state of the world, are irrelevant from the point of view of the prediction.”

“There are no fixtures in nature. The universe is fluid and volatile. Permanence is but a word of degrees. Our globe seen by God is a transparent law, not a mass of facts. The law dissolves the fact and holds it fluid.”
