“No reference is truly direct—every reference depends on some kind of coding scheme. It's just a question of how implicit it is.”

Context: An important distinction exists between prospective and retrospective methods of calculating economic quantities such as incomes, savings, and investments; and... a corresponding distinction of great theoretical importance must be drawn between two alternative methods of defining these quantities. Quantities defined in terms of measurements made at the end of the period in question are referred to as ex post; quantities defined in terms of action planned at the beginning of the period in question are referred to as.

Context: We, politely referred to as "underdeveloped," in truth are colonial, semi-colonial or dependent countries. We are countries whose economies have been distorted by imperialism, which has abnormally developed those branches of industry or agriculture needed to complement its complex economy. “Underdevelopment,” or distorted development, brings a dangerous specialization in raw materials, inherent in which is the threat of hunger for all our peoples. We, the “underdeveloped,” are also those with the single crop, the single product, the single market. A single product whose uncertain sale depends on a single market imposing and fixing conditions. That is the great formula for imperialist economic domination.

Context: Academic scientists of any sort expect to be struck by lightning if they celebrate real creation de novo in the world. One does not expect modern scientists to address creation by God. They have a right to their professional figments such as infinite multiple parallel universes. But it is a strange testimony to our academic life that they also feel it necessary of entrepreneurship to chemistry and cuisine, Romer finally succumbs to the materialist supersition: the idea that human beings and their ideas are ultimately material. Out of the scientistic fog there emerged in the middle of the last century the countervailling ideas if information theory and computer science. The progenitor of information theory, and perhaps the pivotal figure in the recent history of human thought, was Kurt Gödel, the eccentric Austrian genius and intimate of Einstein who drove determinism from its strongest and most indispensable redoubt; the coherence, consistency, and self-sufficiency of mathematics.
Gödel demonstrated that every logical scheme, including mathematics, is dependent upon axioms that it cannot prove and that cannot be reduced to the scheme itself. In an elegant mathematical proof, introduced to the world by the great mathematician and computer scientist John von Neumann in September 1930, Gödel demonstrated that mathematics was intrinsically incomplete. Gödel was reportedly concerned that he might have inadvertently proved the existence of God, a faux pas in his Viennese and Princeton circle. It was one of the famously paranoid Gödel's more reasonable fears. As the economist Steven Landsberg, an academic atheist, put it, "Mathematics is the only faith-based science that can prove it."
