If our moral ideal does not come by the special revelation of God, as the dogmatic religions maintain, and if we cannot find it in nature, if it is beyond the ken of human cognition, if it is unascertainable by science, whence does it come? Professor Adler says:
"We must, indeed, be always on our guard, lest we confuse the idea of the Perfect with notions of the good derived from human experience. This has been the mistake of theology in the past, the point wherein every theodicy has invariably broken down. When we think of the Perfect we think of a transcendental state of existence, when we think of the moral law in its completeness we think of a transcendental law, a law which can only be wholly fulfilled in the regions of the Infinite, but which can never be fully realised within the conditions of space and time. The formula of that law when applied to human relations, yields the specific moral commandments, but these commandments can never express the full content, can never convey the far off spiritual meanings of the supreme law itself. The specific commandments do, indeed, partake of the nature of the transcendental law, they are its effects. The light that shines through them comes from beyond, but its beams are broken as they pass our terrestrial medium, and the full light in all its glory we can never see."
In this passage I believe to recognise the influence of Kant's transcendentalism. I differ from Professor Adler's conception of Kantian transcendentalism, but that is of no account here. One point only is of consequence. Professor Adler uses the word transcendental in the sense of transcendent and thus he changes the ethics of pure reason into mysticism. Professor Adler says:
"Though I can never be scientifically certain, I can be morally sure that the mystery of the universe is to be read in terms of moral perfection."
I do not deny that moral instinct ripens quicker than scientific comprehension. Why? Because in a time when science is not as yet so far advanced as to understand the operations of the moral law, those people who instinctively obey the rules that can be derived from the moral law, will survive and all the rest will go to the wall. But the fact that we can have a reliable moral guide in an instinctive certainty which is generally called conscience, even before we attain to scientific clearness, does not prove that science will be forever excluded from the world of moral ideals.
Professor Adler's agnosticism found a very strong expression in a poem which resembles in its tone and ideas the church hymns of the New Jerusalem. The poem is very unequivocal on the point that moral action is comparable to building an ideal city, the plan of which is unknown to the builders. Professor Adler says:
"Have you heard the Golden City
Mentioned in the legends old?
Everlasting light shines o'er it,
Wondrous tales of it are told.
Only righteous men and women
Dwell within its gleaming wall;
Wrong is banished from its borders,
Justice reigns supreme o'er all.
Do you ask, Where is that City,
Where the perfect Right doth reign?
I must answer, I must tell you,
That you seek its site in vain.
You may roam o'er hill and valley,
You may pass o'er land and sea,
You may search the wide earth over,—
'T is a City yet to be!
