“The great thing, then, in all education, is to make our nervous system our ally instead of our enemy.”

Context: I hold with respect to alliances, that England is a Power sufficiently strong, sufficiently powerful, to steer her own course, and not to tie herself as an unnecessary appendage to the policy of any other Government. I hold that the real policy of England—apart from questions which involve her own particular interests, political or commercial—is to be the champion of justice and right; pursuing that course with moderation and prudence, not becoming the Quixote of the world, but giving the weight of her moral sanction and support wherever she thinks that justice is, and wherever she thinks that wrong has been done... I say that it is a narrow policy to suppose that this country or that is to be marked out as the eternal ally or the perpetual enemy of England. We have no eternal allies, and we have no perpetual enemies. Our interests are eternal and perpetual, and those interests it is our duty to follow.... And if I might be allowed to express in one sentence the principle which I think ought to guide an English Minister, I would adopt the expression of Canning, and say that with every British Minister the interests of England ought to be the shibboleth of his policy.

Context: As you are aware, no perceptions obtained by the senses are merely sensations impressed on our nervous systems. A peculiar intellectual activity is required to pass from a nervous sensation to the conception of an external object, which the sensation has aroused. The sensations of our nerves of sense are mere symbols indicating certain external objects, and it is usually only after considerable practice that we acquire the power of drawing correct conclusions from our sensations respecting the corresponding objects.

Context: Together, we will reclaim America’s schools, before ignorance and apathy claim more young lives. We will reform Social Security and Medicare, sparing our children from struggles we have the power to prevent. And we will reduce taxes, to recover the momentum of our economy and reward the effort and enterprise of working Americans. We will build our defenses beyond challenge, lest weakness invite challenge. We will confront weapons of mass destruction, so that a new century is spared new horrors. The enemies of liberty and our country should make no mistake: America remains engaged in the world by history and by choice, shaping a balance of power that favors freedom. We will defend our allies and our interests. We will show purpose without arrogance. We will meet aggression and bad faith with resolve and strength. And to all nations, we will speak for the values that gave our nation birth.
