The term "method" of realist phenomenology and philosophy can refer to three kinds of things which are being explored extensively in this work: (1) Kinds of philosophical knowledge used to return to things themselves: intellectual "vision" of necessary intelligible essences, insights into necessary states of affairs, knowledge of less than necessary essences, knowledge of existence as such, of the ego cogitans and of a concretely existing world, other persons, and the absolute being, deductive forms of reasoning, and others. (2) Ways to achieve such knowledge: such as various types of distinctions, asking proper questions, correct use of analogies, and replies to objections. (3) Finally, these methods include several "tricks" and devices such as methodic doubt and epoché; these are subordinated to the other methods, and neither necessary nor universal tools of all philosophical knowledge.
