"But reflection plows a deeper furrow, Sir Thomas. Even in the exercise of any one of these five senses it is certain that we are excelled by what we vaingloriously call the lower forms of life. A dog has powers of scent we cannot reach to, birds hear the crawling of a worm, insects distinguish those rays in the spectrum which lie beyond violet and red, and are invisible to us; and snails and fish and ants--perhaps all other living creatures, indeed--have senses which man does not share at all, and has no name for. Granted that we human beings alone possess the power of reasoning, the fact remains that we invariably start with false premises, and always pass our judgments when biased at the best by incomplete reports of everything in the universe, and very possibly by reports which lie flat-footedly." You saw that Browne was troubled. Now he rose. "Nothing will come of this. I do not touch upon the desirability of conquering those fields at which we dare only to hint. No, I am not afraid. I dare assist you in doing anything Dr. Herrick asks, because I know that nothing will come of such endeavors. Much is permitted us--'but of the fruit of the tree which is in the midst of the garden, God hath said, to us who are no more than human, Ye shall not eat of it.'" "Yet Dr. Herrick, as many other men have done, thought otherwise. I, too, will venture a quotation. 'Didst thou never see a lark in a cage? Such is the soul in the body: this world is like her little turf of grass, and the heavens o'er our heads, like her looking-glass, only gives us a miserable knowledge of the small compass of our prison.' Many years ago that lamentation was familiar. What wonder, then, that Dr. Herrick should have dared to repeat it yesterday? And what wonder if he tried to free the prisoner?" "Such freedom is forbidden," Sir Thomas stubbornly replied. "I have long known that Herrick was formerly in correspondence with John Heydon, and Robert Flood, and others of the Illuminated, as they call themselves. There are many of this sect in England, as we all know; and we hear much silly chatter of Elixirs and Philosopher's Stones in connection with them. But I happen to know somewhat of their real aims and tenets. I do not care to know any more than I do. If it be true that all of which man is conscious is just a portion of a curtain, and that the actual universe in nothing resembles our notion of it, I am willing to believe this curtain was placed there for some righteous and wise reason. They tell me the curtain may be lifted. Whether this be true or no, I must for my own sanity's sake insist it can never be lifted." "But what if it were not forbidden? For Dr. Herrick asserts he has already demonstrated that." Sir Thomas interrupted, with odd quickness. "True, we must bear it in mind the man never married--Did he, by any chance, possess a crystal of Venice glass three inches square?"
