Neither logic is unconnected with life nor life is averse to logic. However, there are two additional senses in which Philosophy is used in Jainism, which are peculiar to its own. Infact, here we get the definition of Samyak-darsana which means conviction in the knowledge of things ascertained as they are. Tattvartha Sraddhanam is Samyak-darsanam. This is the first of the trio of the Right Belief, Right Knowledge and Right Conduct, together which constitute the path of liberation.
Faith is the precursor to knowledge.
The Gita also says that he who has faith attains wisdom or knowledge. Faith is not blind belief, but it is the psychological condition of knowledge. Not only knowledge, faith is necessary even for attaining the highest degree of Yoga, and the worlds of righteousness. Even sacrifice becomes void which is empty of faith. Man is of the nature of his faith, what his faith is, that verily, he is.
