In 2014, then government adviser Martin Narey endorsed comments suggesting that "the concentration on non-oppressive practice [happens] at the expense of understanding practicalities about the job".
So engineers have looked at the practicality of non-chemical propulsion: fission or fusion rockets (barely adequate for the nearest stars), or the motive power of the fictional Enterprise -- matter-antimatter fuel.

It's a decade since Sweden's biggest export (literally) stormed the SUV market by offering a previously untried blend of non-aggressive yet rugged styling and family-friendly practicality with ferocious off-road capability.
In this work, numerical simulations of input forces estimation of non-linear lumped-mass systems are performed to verify the practicality and accuracy of the proposed algorithm.
So perhaps non-naturalists should instead either try to accommodate Smith's practicality requirement on moral judgement without committing themselves to a form of judgement internalism as strong as the one Mackie seemed to have in mind or argue against the practicality requirement.
These results demonstrate the practicality of an ab initio strategy for discovering imprinted genes in non-eutherian mammals and, potentially, non-mammalian species as well.
