What probabilists skip is the linkage between propositions derived from observations of phenomena, and the implications of these propositions allowing us to draw conclusions about legal liability.
Probabilists of all stripes will appreciate Lindley's description of the palpable angst experienced by many of the principals as they contended with the realization that the scientific method was abandoning them only to be superseded by a disquieting uncertainty.

Second, even if analysis shows that some historical figures did not accept all of the central premises of the standard modern theory of probability, a comparison of the principles favored by such historical figures and those embraced by conventional modern probabilists could throw historical conceptions of evidence and proof into sharper relief and thus make them more transparent and more intelligible to a modern observer.
The probabilist might assume that when you know nothing, the rational starting point is 50% (thus, many a Bayesian would make 50% the initial prior probability).
