The individual should, prior to engaging in the study of any subject, ask himself what its uses are and what fruit and result will derive from it. If it is a useful branch of knowledge, that is, if society will gain important benefits from it, then he should certainly pursue it with all his heart. If not, if it consists in empty, profitless debates and in a vain concatenation of imaginings that lead to no result except acrimony, why devote one’s life to such useless hairsplittings and disputes. ‘Abdu’l Bahá.
