The scientific study of labor economics provided the opportunity for me to unite theory with evidence my lifetime intellectual passion.
Economic theory is the most prestigious subject of instruction and study. Agricultural economics, labor economics and marketing are lower caste fields of study.
I started in the law; and the study of law, when it precedes the study of economics, gives you a set of foundation principles about how human beings interact. Economics is very useful, and I studied economics in graduate school. But without understanding the social and organizational context of economics, it becomes a theory without any groundwork.
Evidence-based reasoning underpins all scientific thinking, and it involves testing hypotheses or theories against data. Validating a theory requires replicable measurements from independent groups with different equipment and methods of analysis. Convergence of evidence is critical to the acceptance of a scientific idea.
Home economics should find its way into the curriculum of every school because the scientific study of a problem pertaining to food, shelter or clothing... raises manual labor that might be drudgery to the plane of intelligent effort that is always self-respecting...Home economics is not one department, in the sense in which dairying or entomology or soils is a department. It is not a single speciality... Many technical and educational departments will grow out of it as time goes on.
A theory is only as good as its assumptions. If the premises are false, the theory has no real scientific value. The only scientific criterion for judging the validity of a scientific theory is a confrontation with the data of experience.
Through this additional support, we must renew our commitment to provide talented young people with the opportunity to build scientific careers based on their curiosity, the same opportunity that was provided to me when I began my work.
The theory that the biosphere was created without evolution, a few thousand years ago, is ruled out by overwhelming scientific evidence. To claim that there are 'alternative (always better) Biblical explanations of the same data', which make creationism a reasonable alternative to our best theories of biology and physics, is appalling intellectual dishonesty.
The real scientific study of the distribution of wealth has, we must confess, scarcely begun. The conventional academic study of the so-called theory of distribution into rent, interest, wages, and profits is only remotely related to the subject. This subject, the causes and cures for the actual distribution of capital and income among real persons, is one of the many now in need of our best efforts as scientific students of society.
I had become interested in economics, an interest that was transformed into a lifetime dedication when I met with the mathematical theory of general economic equilibrium.
Mainstream economics scholarship produces theory without facts ("pure theory") and facts without theory ("applied economics").
Harvard Law provided an opportunity to learn from a faculty that had shaped the laws of our country and helped to change the world around us. It also offered an opportunity to study with the brightest students and to test myself against the best.
People sometimes try to score debating points by saying, Evolution is only a theory. That is correct, but it's important to understand what that means. It is also only a theory that the world goes round the Sun - it's just a theory for which there is an immense amount of evidence. There are many scientific theories that are in doubt. Even within evolution, there is some room for controversy. But that we are cousins of apes and jackals and starfish, let's say, that is a fact in the ordinary sense of the word.
My provocative statement is that we desperately need a serious, scientific theory of cities and scientific theory means quantifiable, relying on underlying generic principles that can be made in a - put into a predictive framework. That's the quest.
It is clear that Economics, if it is to be a science at all, must be a mathematical science ... simply because it deals with quantities... As the complete theory of almost every other science involves the use of calculus, so we cannot have a true theory of Economics without its aid.
Well, it [evolution] is a theory, it is a scientific theory only, and it has in recent years been challenged in the world of science and is not yet believed in the scientific community to be as infallible as it once was believed. But if it was going to be taught in the schools, then I think that also the biblical theory of creation, which is not a theory but the biblical story of creation, should also be taught.
If the evidence says you're wrong, you don't have the right theory. You change the theory, not the evidence.
