"The function of enlightenment is to recognize that no phenomenon can be an effect which has not another phenomenon as its cause, and to search for the sole cause of every effect, noting all its parts and their consecutive divisions."
These words describe the mental work performed by the human brain fairly well, but still they require a little addition, to the effect that the mental work is no exception from any other phenomena, all of which have not alone their special, but also one general cause. The cause of all causes, of which religion is making an idol, must be profaned, so to speak, by the cult of science, so that the above definition of Lazarus regarding enlightenment would read as follows: The sole and true cause of all effects is the universe, or the general interdependence of all things. But this is not by far the full scope of enlightenment. It is further necessary, as Lazarus well says, to note "all its parts and their consecutive divisions." We further add: The universal cause must be understood not alone in its consecutive parts, but also in its co-ordinate parts. It is only then that understanding, enlightenment, become perfect. We then find that after all the relation between cause and effect, or the relation between the universal truth and its natural phenomena, is not a very trenchant one, but a relative one.
"Enlightenment advances in various, in all, fields of mental life. Religious enlightenment has long been recognized as the most essential, justly so, and for many reasons, the chief of them being that religious enlightenment is the most important and hence the most bitterly contested."
Thus religious enlightenment is a part of universal, cosmic, enlightenment. It is a confusing expression to say that it is confined to "all fields of mental life." We believe to be shedding more light on the question by saying that there is enlightenment in all fields, not alone in the mental, but also in the cosmic, which unites both the material and mental. To classify this field, that is the exhaustive task of our understanding, that its exhaustive definition.
XI THE DISTINCTION BETWEEN CAUSE AND EFFECT IS ONE OF THE MEANS OF UNDERSTANDING
The processes of the human mind and their subjective composition cannot be analyzed in a pure state and without regard to their objective effects any more than handiwork can be explained without the raw material to be handled and the products derived therefrom, any more than any work can be described in a pure state without regard to the product.
That is the sad defect of old time logic which is an obstacle to its further advance: it literally tears things out of their connections and forgets the necessity of interdependence over the need of special study.
The instrument which produces thought and knowledge in the human brain is not an isolated thing, nor an isolated quality. It is connected not only with the brain and the nervous system, but also with all qualities of the soul. True, thinking is different from feeling, but it is nevertheless a feeling the same as gladness and sorrow. Thought is called incomprehensible and the heart unfathomable. It is the function of science, of thinking and thought, to fathom and comprehend what as yet is not fathomed and not comprehended.
Just as thinking and understanding are parts of the human soul, so the latter is a part of physical and intellectual man. Together with the physical development of man, of the species as well as of the individual, the soul also develops and with it that part which is the special object of the theory of understanding, viz., thought and thinking. Not alone does physical development produce intellectual development, but, vice versa, the understanding reacts on the physical world. The one is not merely a cause, nor the other merely an effect. This obsolete distinction does not suffice for the full understanding of their interrelations. We pay a tribute to the "thoughts on enlightenment" of Professor Lazarus quoted in the previous chapter by acknowledging that they throw so much light on a certain point that little more than the dot over the "i" is required in order to clear up a bad misunderstanding about the relation of cause and effect.
