Religion is the subjective experience. Science is the objective reality. To argue either is a ridiculous waste of time and energy.
I would have the studies elective. Scholarship is to be created not by compulsion, but by awakening a pure interest in knowledge. The wise instructor accomplishes this by opening to his pupils precisely the attractions the study has for himself. The marking is a system for schools, not for the college; for boys, not for men; and it is an ungracious work to put on a professor.
The more you travel, the better you get at it. It sounds silly, but with experience you learn how to pack the right way. I remember one of my first trips abroad, travelling around Europe by rail, fresh out of high school. I brought all these books with me and a paint set. I really had too much stuff, so I've learnt to be more economical.
