Abstract

Philosophy of rationalism is an understanding in philosophy that says the most important tool for
obtaining and disseminating knowledge is reason or reason. Rationalism believes that the way to
achieve knowledge is to rely on logic and intellect. This study aims to look at the philosophy that
is the basis of the formation of science. The research approach that researchers use in writing
scientific papers is a type of library research. Humans use their minds to capture and find
knowledge. The flow of rationalism believes that truth exists in human reason and cannot be
based on a lie, because reason is a creation of God given to humans and there is no possibility
of a lie. Rationalism is something that makes reason or reason the source of all knowledge, which
is obtained by the way we think. This is what became the basis or initially emerged science and
in the and there is science that emerges from the results of the philosophy of rationalism that we
can feel until now, such as mathematics which is all accepted as absolute truth so that it can be
concluded that the philosophy of rationalism is a basis of truth. which focuses on reason or the
ratio that creates knowledge.
