There is indeed a fundamental beauty in mathematical abstractions. They so attracted the Greek philosopher Plato that he declared that all those things that we can see and touch are, in fact, mere shadows of the true reality and that the real things of this universe can be found only through the use of pure reason. Plato's knowledge of mathematics was relatively naive, and many of the cherished purities of Greek mathematics have been shown to be flawed.
The early years of statistical development were dominated by men. Many women were working in the field, but they were almost all employed in doing the detailed calculations needed for statistical analysis, and were indeed called "computers".
Women tended to be more docile and patient, so went the belief, and could be depended upon more than men to check and recheck the accuracy of their calculations. A typical picture of the Galton Biometrical Laboratory under Karl Pearson would have Pearson and several men walking around, looking at output from the computers or discussing deep mathematical ideas, while all about them rows of women were computing.

Probit analysis provides a mathematical foundation for the doctrine first established by the sixteenth-century physician Paracelsus: "Only the dose makes a thing not a poison." Under the Paracelsus doctrine, all things are potential poisons if given in a high enough dose, and all things are nonpoisonous if given in a low enough dose. To this doctrine, Bliss added the uncertainty associated with individual results. One reason why many foolish users of street drugs die or become very sick on cocaine or heroin or speed is that they see others using the drugs without being killed. They are like Bliss's insects. They look around and see some of their fellow insects still alive. However, knowing that some individuals are still living provides no assurance that a given individual will survive. There is no way of predicting the response of a single individual.
