if you don't know any of the theory behind a problem, you don't even necessarily know if theres a solution thats useful in practice. A good example in Computer Science is the various reductions (efficient or not )between different problems, where you relate the difficulty of the problem to any other computational problem which you find you're able to encode within the structure of the orginal problem.
