Philosophy has no meaning at all if not universal, both in scope and in spirit. The study of philosophy should help people to build on the basis of religious beliefs intellectually mature. Philosophy can support a person's religious beliefs, so long as those beliefs do not depend on the conception prailmiah are outdated, narrow and dogmatic. Affairs (concerns) is the main religion of harmony, arrangement, bond, devotion, peace, honesty, liberation, and God.

In contrast to the opinion of Soemadi Soerjabrata, namely studying philosophy is to Sharpening mind, then H. De Vos argues that philosophy is not only well known, but must be practiced in everyday life. People expect that the philosophy will give him the basics of knowledge, which is needed to live well. Philosophy must teach man how he should live well. Philosophy must teach man how he should live in order to be a good human being and happy. From the above it can be concluded that the purpose of philosophy is to find the true nature of things, both in logic (truth thinking), ethics (behavior), or metaphysical (the nature of authenticity).
