Now, it being established that the Law makes the observation and consideration of creation by reason obligatory--and consideration is nothing but to make explicit the implicit--this can only be done through reason. Thus we must look into creation with the reason. Moreover, it is obvious that the observation which the Law approves and encourages must be of the most perfect type, performed with the most perfect kind of reasoning. As the Law emphasises the knowledge of God and His creation by inference, it is incumbent on any who wish to know God and His whole creation by inference, to learn the kinds of inference, their conditions and that which distinguishes philosophy from dialectic and exhortation from syllogism. This is impossible unless one possesses knowledge beforehand of the various kinds of reasoning and learns to distinguish between reasoning and what is not reasoning. This cannot be done except one knows its different parts, that is, the different kinds of premises. Hence, for a believer in the Law and a follower of it, it is necessary to know these things before he begins to look into creation, for they are like instruments for observation. For, just as a student discovers by the study of the law, the necessity of knowledge of legal reasoning with all its kinds and distinctions, a student will find out by observing the creation the necessity of metaphysical reasoning. Indeed, he has a greater claim on it than the jurist. For if a jurist argues the necessity of legal reasoning from the saying of God: “Wherefore take example _from them_ O ye who have eyes,”[8] a student of divinity has a better right to establish the same from it on behalf of metaphysical reasoning.
