Science and Subjectivity.

I've read dozens of works on the philosophy of science by all the major philosophers and scientists who have written on the subject and Scheffler's short work is the most concise, pithy, and cogent work I've seen. I underlined just about every other sentence, because he comes up with these great, pithy little statements that condense what other authors would take a whole paragraph to say. Super little book on the subject and a great way to get yourself started in this big and important area.
