From the Author Finality and Intelligence. The book is an evaluation and analysis of the last Way of the known Five Ways leading the human mind to the existence of God elaborated by Saint Thomas Aquinas. The Fifth Way will be considered within general context of Thomistic philosophy. It is not the intention to analyze all Five Ways of Thomas but center on the mind from orderliness of the finite beings observed in this world towards final infnite intelligence of the First Mover and the First Creative Cause of the world. The analysis is done on the metaphysical level; it acknowledges the right of the human mind to complete intelligibility of being as such and the power of the mind to answer the ultimate questions to which of course belongs the problem of the existence of God.
