There are two kinds of thinkers, scholars and scientists. The first are the 'trail blazers' who propose new revolutionary ideas, point to new directions for scientific and intellectual developments, create new paradigms of science and scholarship, but leave the details to others. The second are those who follow the new trail, carry out careful experimentation and research within the established paradigm, and work out the precise formulations of theories in a particular domain of knowledge.
