The climax of mind is Intellect. Physical changes accompany thought but cannot measure it. Relations of thought and feeling. _Truth_ is its only measure. Truth, like pleasure, is desired for its preservative powers. It is reached through the laws of thought. These laws are: (1) the natural order of the association of ideas, (2) the methods of applied logic, (3) the forms of correct reasoning. The last allow of mathematical expression. They are three in number, called those of Determination, Limitation and Excluded Middle. The last is the key-stone of religious philosophy. Its diverse interpretations. Its mathematical expres ion[TN-1] shows that it does not relate to contradictories. But certain concrete analytic propositions, relating to contraries, do have this form. The contrary as distinguished from the privative. The Conditioned and Unconditioned, the Knowable and Unknowable are not true contradictions. The synthesis of contraries is theoretic only. Errors as to the limits of possible explanation corrected by these distinctions. The formal law is the last and complete explanation. The relations of thought, belief and being. THE RELIGIOUS SENTIMENT. CHAPTER I. THE BEARING OF THE LAWS OF MIND ON RELIGION. The Science of Religion is one of the branches of general historical science. It embraces, as the domain of its investigation, all recorded facts relating to the displays of the Religious Sentiment. Its limits are defined by those facts, and the legitimate inferences from them. Its aim is to ascertain the constitutive laws of the origin and spread of religions, and to depict the influence they have exerted on the general life of mankind. The question whether a given religion is true or false cannot present itself in this form as a proper subject of scientific inquiry. The most that can be asked is, whether some one system is best suited to a specified condition of the individual or the community. The higher inquiry is the object of the Philosophy of Religion. This branch of study aims to pass beyond recorded facts and local adjustments in order to weigh the theoretical claims of religions, and measure their greater or less conformity with abstract truth. The formal or regulative laws of religious thought occupy it. Theology, dogmatic or polemic, is an explanatory defence of some particular faith. Together with mythology and symbolism, it furnishes the material from which the Science and Philosophy of Religion seek to educe the laws and frame the generalizations which will explain the source and aim of religion in general. The common source of all devotional displays is the Religious Sentiment, a complex feeling, a thorough understanding of which is an essential preliminary to the study of religious systems.
