“It is safer to try to understand the low in the light of the high than the high in the light of the low.”

Leo Strauss (1899–1973) Classical philosophy specialist and father of neoconservativism

Context: It is safer to try to understand the low in the light of the high than the high in the light of the low. In doing the latter one necessarily distorts the high, whereas in doing the former one does not deprive the low of the freedom to reveal itself as fully as what it is.

“Firms that have a high BE/ME (a low stock price relative to book value) tend to have low earnings on assets. Conversely, low BE/ME (a high stock price relative to book value) is associated with persistently high earnings.”

“Innovative e-business projects start with a design of the e-business model. We often encounter the view, in research as well as industry practice, that an e-business model is similar to a business process model, and so can be specified using UML activity diagrams or Petri nets. In this paper, we explain why this is a misunderstanding. The root cause is that a business model is not about process but about value exchanged between actors. Failure to make this separation of concerns leads to poor business decision-making and inadequate business requirements.”

“The classical support for as-if models in the social sciences stems from the economist Milton Friedman (1953), who, like the psychologist B. F. Skinner, saw little value in modeling cognitive processes. In contrast, our aim is to understand actual decision processes, not only the outcomes. There is a good reason for this. Without modeling the cognitive blade of Simon's scissors, it is utterly impossible to determine in what environments heuristics succeed, that is, their ecological rationality.”

“The usefulness of the models in constructing a testable theory of the process is severely limited by the quickly increasing number of parameters which must be estimated in order to compare the predictions of the models with empirical results.”
