The purpose of this article is to show possible relationships between the God who is given to man in religious experience and the so-called God of philosophers. The starting point of author's analyses is the belief that, first of all, God is given to man in his intimate space of religious experience. The second premise of his considerations is the belief that God goes beyond this experience and is given as an 'evasive presence'. God is something more than what is just given in religious experience. In this way of thinking something more is opened; it is also the way of philosophy, it is the way towards the Other. This make it possible to ask another question - how is it possible for the philosophy of the Other not to become a philosophy of the Alien. The article tries to give an answer to this question.
