Abstract
This article explores the possibility of a phenomenological method in the field of philosophy of science. It reconstructs the idea of scienticity, which is significant both for philosophy as a science and for philosophy's relationship to nonphilosophical sciences. The concepts of intentionality, eidetic objectness, and absolute evidence are discussed as conditions for the possibility of philosophy as a rigorous science. The concepts of constituting, objectivation, and regional ontology are examined in the context of the possibility of founding of sciences with a dogmatic standpoint in philosophy. It is suggested that the phenomenological program of philosophy of science remains current, though it also continues a tradition of thinking about science that stretches back to Plato. Phenomenological philosophy of science is a clarification of the meaning of scienticity, the very principles of a scientific relationship to the world.
