http://www.sparknotes.com/philosophy/problems/section15/ The aim of philosophy is the achievement of knowledge through criticism, "which gives unity and system to the body of sciences." However, philosophy does not maintain a substantial body of definite knowledge in the sense that history, mathematics, or the physical sciences do. Part of the reason why philosophy does not bear such a body of evidence is because when definite knowledge on a subject becomes possible, it splits off forming another discipline. Study of the heavens, of natural sciences, and the human mind originated in philosophic investigation and now assume the figures of astronomy, physics, and psychology. Thus, with respect to definite answers, "the uncertainty of philosophy is more apparent than real."

Yet, part of the uncertainty in philosophy derives from the very nature of the questions that it undertakes to answer. These questions address most profound human interests: "Has the universe any unity of plan or purpose, or is it a fortuitous concourse of atoms? Is consciousness a permanent part of the universe, giving hope of indefinite growth in wisdom, or is it a transitory accident on a small planet on which life must ultimately become impossible? Are good and evil of importance to the universe or only to man?" Besides the magnitude of these questions, the various answers which philosophy suggests are usually not "demonstrably true." Still, the pursuit of philosophy is not merely to suggest answers to these questions but to make us sensitive to their importance and to keep us conscious of a "speculative interest in the universe," which we might otherwise forget.

Even though some philosophers have developed programs of thought that do offer a definite set of conclusions about religious belief, human knowledge, and other issues, Russell urges that such attempts are usually unwise dogmatic declarations. Consistent with the thought of his other chapters, he claims that we cannot hope for definite answers or even high degrees of certainty.
