The radicalism of this approach risks cancelling any other thoughts, and this becomes a big problem because it excludes "the validity to deduce our principles from the natural world, unconcerned by its derision and reaffirming its neglected validity" (Havel, 2014).

Although ethical reasoning cannot be used to deduce from first principles what practices should be undertaken in all circumstances, it can establish parameters that bound what sorts of practices are acceptable or unacceptable in certain types of scenarios.
While ethical reasoning cannot be used to deduce from first principles what practices should be undertaken in every given set of circumstances, it can establish parameters that bound what sorts of practices will be acceptable or unacceptable in certain types of scenarios.
Every geometric detail of the optimized flow structure is deduced from principle.

In the beginning was Keynesian economics, which was ad hoc in the sense that on some important issues it relied on observed stylized facts rather than trying to deduce everything from first principles.
In a joint work with Pablo Groisman, Ruojun Huang and Vladas Sidoravicius, we establish for such models an averaging principle and deduce from it the convergence of the normalized domain boundary, to a limiting shape.
