Meaning of philosophy its relation with science and religion?

to my mind, philosophy, religion, and science, have the same purpose and end- to search what

is true. philosophy tends to answer questions about reality, knowledge, morality, truth, and

beauty, using reason. reason is the only tool that shall be used in attaining truth, how we use

it to know the underlying structure of what exists and of materials provided to us. this makes it

different from others, as long as possible, it doesn't hold

anything from mysticism and faith (which are matters of religion), and confines itself not only

to the observable reality (which is the starting point of science). whereas religion explains the

cosmic purpose, and science the cosmic order, philosophy explains both.
