Economics is an interesting science. For me, one of its appeals is its dual nature; it makes use of both sides of the brain. In some ways, it has elements of a hard science, mathematical models, empirical data, etc. However, at its core, it is a social science. We can see an example of this in the concept of value. It can be both intangible and tangible. The value of a human life is subjective.
The most merciful thing in the world, I think, is the inability of the human mind to correlate all its contents. We live on a placid island of ignorance in the midst of black seas of infinity, and it was not meant that we should voyage far. The sciences, each straining in its own direction, have hitherto harmed us little; but some day the piecing together of dissociated knowledge will open up such terrifying vistas of reality, and of our frightful position therein, that we shall either go mad from the revelation or flee from the light into the peace and safety of a new dark age.
