“We know that energy can not be created nor destroyed but can be changed in it's form. If it can not be formed then it can not exist. We may not exist.”

“Energy cannot be created or destroyed, but can change it's form.”

“Energy cannot be created or destroyed, it can only be changed from one form to another.”

“Dagny, we can never lose the things we live for. We may have to change their form at times, if we've made an error, but the purpose remains the same and the forms are ours to make.”

“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.”

“We fill pre-existing forms and when we fill them change them and are changed.”
