„No event can be fairly judged without background and perspective.“

—  Aleister Crowley poet, mountaineer, occultist 1875 - 1947
Context: To read a newspaper is to refrain from reading something worth while. The natural laziness of the mind tempts one to eschew authors who demand a continuous effort of intelligence. The first discipline of education must therefore be to refuse resolutely to feed the mind with canned chatter. People tell me that they must read the papers so as to know what is going on. In the first place, they could hardly find a worse guide. Most of what is printed turns out to be false, sooner or later. Even when there is no deliberate deception, the account must, from the nature of the case, be presented without adequate reflection and must seem to possess an importance which time shows to be absurdly exaggerated; or vice versa. No event can be fairly judged without background and perspective. Ch. 23.

„No philosophy can ever be anything but a summary sketch, a picture of the world in abridgment, a foreshortened bird's-eye view of the perspective of events.“

—  William James American philosopher, psychologist, and pragmatist 1842 - 1910
Context: Reduced to their most pregnant difference, empiricism means the habit of explaining wholes by parts, and rationalism means the habit of explaining parts by wholes. Rationalism thus preserves affinities with monism, since wholeness goes with union, while empiricism inclines to pluralistic views. No philosophy can ever be anything but a summary sketch, a picture of the world in abridgment, a foreshortened bird's-eye view of the perspective of events. And the first thing to notice is this, that the only material we have at our disposal for making a picture of the whole world is supplied by the various portions of that world of which we have already had experience. We can invent no new forms of conception, applicable to the whole exclusively, and not suggested originally by the parts. All philosophers, accordingly, have conceived of the whole world after the analogy of some particular feature of it which has particularly captivated their attention. Thus, the theists take their cue from manufacture, the pantheists from growth. For one man, the world is like a thought or a grammatical sentence in which a thought is expressed. For such a philosopher, the whole must logically be prior to the parts; for letters would never have been invented without syllables to spell, or syllables without words to utter. Another man, struck by the disconnectedness and mutual accidentality of so many of the world's details, takes the universe as a whole to have been such a disconnectedness originally, and supposes order to have been superinduced upon it in the second instance, possibly by attrition and the gradual wearing away by internal friction of portions that originally interfered. Another will conceive the order as only a statistical appearance, and the universe will be for him like a vast grab-bag with black and white balls in it, of which we guess the quantities only probably, by the frequency with which we experience their egress. For another, again, there is no really inherent order, but it is we who project order into the world by selecting objects and tracing relations so as to gratify our intellectual interests. We carve out order by leaving the disorderly parts out; and the world is conceived thus after the analogy of a forest or a block of marble from which parks or statues may be produced by eliminating irrelevant trees or chips of stone. Some thinkers follow suggestions from human life, and treat the universe as if it were essentially a place in which ideals are realized. Others are more struck by its lower features, and for them, brute necessities express its character better. All follow one analogy or another; and all the analogies are with some one or other of the universe's subdivisions. Every one is nevertheless prone to claim that his conclusions are the only logical ones, that they are necessities of universal reason, they being all the while, at bottom, accidents more or less of personal vision which had far better be avowed as such; for one man's vision may be much more valuable than another's, and our visions are usually not only our most interesting but our most respectable contributions to the world in which we play our part. What was reason given to men for, said some eighteenth century writer, except to enable them to find reasons for what they want to think and do?—and I think the history of philosophy largely bears him out, "The aim of knowledge," says Hegel, "is to divest the objective world of its strangeness, and to make us more at home in it." Different men find their minds more at home in very different fragments of the world. A Pluralistic Universe (1909) http://www.gutenberg.org/files/11984/11984-8.txt, Lecture I

„I'd just like to interject for a moment. What you’re referring to as Linux, is in fact, GNU/Linux, or as I’ve recently taken to calling it, GNU plus Linux. Linux is not an operating system unto itself, but rather another free component of a fully functioning GNU system made useful by the GNU corelibs, shell utilities and vital system components comprising a full OS as defined by POSIX. Many computer users run a modified version of the GNU system every day, without realizing it. Through a peculiar turn of events, the version of GNU which is widely used today is often called “Linux”, and many of its users are not aware that it is basically the GNU system, developed by the GNU Project. There really is a Linux, and these people are using it, but it is just a part of the system they use. Linux is the kernel: the program in the system that allocates the machine’s resources to the other programs that you run. The kernel is an essential part of an operating system, but useless by itself; it can only function in the context of a complete operating system. Linux is normally used in combination with the GNU operating system: the whole system is basically GNU with Linux added, or GNU/Linux. All the so-called “Linux” distributions are really distributions of GNU/Linux.“
