No hay ninguna línea que divida entre ciencia y filosofía, pero los problemas filosóficos tienden a tener tres características especiales. Primero, tienden a tratarse de grandes armazones más que de preguntas específicas dentro del armazón. Segundo, son preguntas para las cuales no hay un método generalmente aceptado para su solución. Y tercero ellos tienden a involucrar asuntos conceptuales.

Thoreau's political writing is intensely personal and direct. Both his life and work focus uncompromisingly on the question 'how should I live?', and for Thoreau, no element of day-to-day existence is left untouched by moral and political issues. This edition of Thoreau's political essays includes 'Civil Disobedience', selections from Walden, 'Life Without Principle', and the anti-slavery addresses, such as 'Slavery in Massachusetts'. In her introduction, Nancy L. Rosenblum places the essays in the context of Thoreau's life of self-examination, and the (...) debates about the abolition of slavery, and she analyses the themes of citizenship and resistance that have made Thoreau an enduring influence in political philosophy and practice.

Based on an 1839 boat trip Thoreau took with his brother from Concord, Massachusetts, to Concord, New Hampshire, and back, this classic of American literature is not only a vivid narrative of that journey, it is also a collection of thought-provoking observations on such diverse topics as poetry, literature and philosophy, Native American and Puritan histories of New England, friendship, sacred Eastern writings, traditional Christianity, and much more. Written, like Walden, while Thoreau lived at Walden Pond, and published in 1849, (...) A Week (his first book) shares many themes with Walden, published in 1854. Both dramatize the process of self-renewal in nature and resolutely rail against the official culture and politics of the "trivial Nineteenth Century." Blending keen observation with a wealth of perceptive and informed reflections, Thoreau develops a continuous and lyrical dialogue between the past and present, as particular scenes on shore trigger reflections on the region’s history and legends. Originally conceived as a travel book, A Week eventually became much more — one of the most intellectually ambitious works of 19th-century America, and a requiem for Thoreau's brother John, who died from a sudden illness in 1842. Of Thoreau and this work, Ralph Waldo Emerson said, "H. D. Thoreau is a great man in Concord, a man of original genius and character.... I think it [A Week...] is a book of wonderful merit, which is to go far and last long.". (shrink)

"The Bush administration and Congress are in concert on the goal of developing a fleet of unmanned aircraft that can reduce both defense costs and aircrew losses in combat by taking on at least the most dangerous combat missions. Unmanned combat aerial vehicles (UCAVs) will be neither inexpensive enough to be readily expendable nor-- at least in early development-- capable of performing every combat mission alongside or in lieu of manned sorties. Yet the tremendous potential of such systems is widely (...) recognized, and allies as well as potential adversaries are moving quickly to mount their own research and development programs. The United States is committed to fielding UCAV capabilities by 2010, principally for the missions of suppression of enemy air defense and deep strike, which are among the highest risk tasks for the Air Force and naval aviation."--Overview.

I wish to speak a word for Nature, for absolute freedom and wildness, as contrasted with a freedom and culture merely civil,—to regard man as an inhabitant, or a part and parcel of Nature, rather than a member of society. I wish to make an extreme statement, if so I may make an emphatic one, for there are enough champions of civilization: the minister and the school committee and every one of you will take care of that.

I HEARTILY accept the motto, “That government is best which governs least;” and I should like to see it acted up to more rapidly and systematically. Carried out, it finally amounts to this, which also I believe,—“That government is best which governs not at all;” and when men are prepared for it, that will be the kind of government which they will have. Government is at best but an expedient; but most governments are usually, and all governments are sometimes, inexpedient. (...) The objections which have been brought against a standing army, and they are many and weighty, and deserve to prevail, may also at last be brought against a standing government. The standing army is only an arm of the standing government. The government itself, which is only the mode which the people have chosen to execute their will, is equally liable to be abused and perverted before the people can act through it. Witness the present Mexican war, the work of comparatively a few individuals using the standing government as their tool; for, in the outset, the people would not have consented to this measure. This American government,—what is it but a tradition, though a recent one, endeavoring to transmit itself unimpaired to posterity, but each instant losing some of its integrity? It has not the vitality and force of a single living man; for a single man can bend it to his will. It is a sort of wooden gun to the people themselves. But it is not the less necessary for this; for the people must have some complicated machinery or other, and hear its din, to satisfy that idea of government which they have. Governments show thus how successfully men can be imposed on, even impose on themselves, for their own advantage. It is excellent, we must all allow. Yet this government never of itself furthered any enterprise, but by the alacrity with which it got out of its way. It does not keep the country free. It does not settle the West. It does not educate. The character inherent in the Ameri-. (shrink)

1. In this essay I want to try out some ideas: about the notion of a right—how it works and the terms of its meaningful application; about a distinction between institutional and noninstitutional rights; in regard to noninstitutional rights, about specific, nonspecific, general, and so-called universal rights; in relation to ‘universal’ institutional rights, about the notions of ‘natural’ and ‘human’ rights; about certain classes of noninstitutional rights which are variously regarded as basic, fundamental, inalienable, etc.; and about certain problems concerning (...) what is sometimes referred to as the metaphysics of rights: problems about their reality or existence, their eternality or historicity. Throughout I shall feel quite free to move back and forth between so-called analytical questions about rights and questions of a more substantive nature. I shall be aiming both at a clarification of my thinking about rights and at a determination of those noninstitutional rights which, in my book, are to be taken most seriously. This essay is thus written, in the first instance, for my own edification. To others I offer it as an invitation to colloquy and to further reflection. But such colloquies and reflections will not serve their purpose unless they are funded back into the practical deliberations and decisions of ordinary life. (shrink)
