I have come to suspect that this long descent down the ladder of life, beautiful and instructive though it may be, will not lead us to the final secret. In fact I have ceased to believe in the final brew or the ultimate chemical. There is, I know, a kind of heresy, a shocking negation of our confidence in blue-steel microtomes and men in white in making such a statement. I would not be understood to speak ill of scientific effort, for in simple truth I would not be alive today except for the microscopes and the blue steel. It is only that somewhere among these seeds and beetle shells and abandoned grasshopper legs I find something that is not accounted for very clearly in the dissections to the ultimate virus or crystal or protein particle. Even if the secret is contained in these things, in other words, I do not think it will yield to the kind of analysis our science is capable of making.
