"Although blinding with science can be used in any argument, many will recognize the special domain of this fallacy as the subjects which like to consider themselves as sciences, but are not.

Science deals with things from atoms to stars at a level where individual differences do not matter. The scientist talks of 'all' rolling bodies or whatever, and formulates general laws to test by experiment.

The trouble with human beings is that, unlike rolling bodies, the individual differences do matter. Often, again unlike rolling bodies, they want to do different things.

Although this might prevent us from being scientific about human beings, it does not stop us pretending to be so. What we do here is to add the word 'science' onto the study, giving us 'economic science', 'political science' and 'social science'. Then we dress them in that white coat of scientific language, and hope that no one will notice the difference."

The statement that all of us are purportedly able to coherently conceive or imagine a certain situation - for instance, an imitation man or a zombie - is rather trivial from a philosophical point of view because ultimately it is just an empirical claim about the history of the brain and its functional architecture. It is a statement about a world that is phenomenally possible for human beings. It is not a statement about the modal strength of the relationship between physical and phenomenal properties; logical possibility (or necessity) is not implied by phenomenological possibility (or necessity). From the simple fact that beings like ourselves are able to phenomenally simulate a certain apparently possible world, it does not follow that a consistent or even only an empirically plausible description of this world exists. -- Thomas Metzinger

Besides porking (really) hot babes, flipping out, wailing on guitars, and cutting off heads, a ninja has to train. They have to meditate ALL THE TIME. But most importantly, each morning a ninja should think about going a little crazier than the day before. Beyond thinking about going berserk, a ninja must, by definition, actually go berserk.

"The demand for immortality is nowadays essentially teleological. We believe ourselves immortal because we believe ourselves fit for immortality. A 'substance' ought to perish we think, if not worthy to survive, and an insubstantial 'stream' to prolong itself where worthy, if the nature of Things is organized in the rational way we trust it is."

--William James, "The Consciousness of Self", The Principles of Psychology

It seems thus impossible that any question about the nature or character of particular sensory qualities should ever arise which is not a question about the differences from (or relations to) other sensory qualities; and the extent to which the effects of its occurrence differ from the effects of the occurrence of any other qualities determines the whole of its character.

To ask beyond this for the explanation of some absolute attribute of sensory qualities seems to be to ask for something which by definition cannot manifest itself in any differences in the consequences which will follow because this rather than any other quality has occurred. Such a factor, however, could by definition not be of relevance to any scientific problem. The 'absolute' quality seems to be unexplainable because there is nothing to explain, because absolute, if it has any meaning at all, can only mean that the attribute which is so described has no scientific significance.

I've never seen a UFO. When I went to places that were rumored to be haunted, nothing showed up. Two hours of intense staring didn't make my pencil move a single millimeter, and glaring at my classmate's head didn't reveal his thoughts to me, either. I couldn't help but get depressed at how normal the laws of physics were.

The unwillingness to tolerate or respect any social forces which are not recognizable as the product of intelligent design, which is so important a cause of the present desire for comprehensive economic planning, is indeed only one aspect of a more general movement. We meet the same tendency in the field of morals and conventions, in the desire to substitute an artificial for the existing languages, and in the whole modern attitude toward processes which govern the growth of knowledge. The belief that only a synthetic system of morals, an artificial language, or even an artificial society can be justified in an age of science, as well as the increasing unwillingness to bow before any moral rules whose utility is not rationally demonstrated, or to conform with conventions whose rationale is not known, are all manifestations of the same basic view which wants all social activity to be recognizably part of a single coherent plan. They are the results of that same rationalistic "individualism" which wants to see in everything the product of conscious individual reason.

A behavioral policy based on an inside strategy permits the alcoholic to sit at the bar and rehearse the reasons to abstain. An outside strategy identifies a principle or rule of conduct that produces the most accurate or desirable available outcome, and sticks to that rule despite the subjective pull to abandon the principle. A behavioral policy based on an outside strategy recommends that you avoid the bar in the first place.

The master mathematician sat in his private room and pushed the papers from him. His calculations were already finished. In a small white phial there still remained a little of the drug that had kept him awake and active for four long nights. Each day, serene, explicit, patient as ever, he had given his lecture to his students, and then had come back at once to this momentous calculation. His face was grave, a little drawn and hectic from his drugged activity. For some time he seemed lost in thought. Then he went to the window, and the blind went up with a click. Half way up the sky, over the clustering roofs, chimneys and steeples of the city, hung the star.

He looked at it as one might look into the eyes of a brave enemy. "You may kill me," he said after a silence. "But I can hold you--and all the universe for that matter--in the grip of this little brain. I would not change. Even now."

-- H.G. Wells, "The Star", 1897

I have met people who exaggerate the differences [between the morality of different cultures], because they have not distinguished between differences of morality and differences of belief about facts. For example, one man said to me, "Three hundred years ago people in England were putting witches to death. Was that what you call the Rule of Human Nature or Right Conduct?" But surely the reason we do not execute witches is that we do not believe there are such things. If we did-if we really thought that there were people going about who had sold themselves to the devil and received supernatural powers from him in return and were using these powers to kill their neighbours or drive them mad or bring bad weather, surely we would all agree that if anyone deserved the death penalty, then these filthy quislings did. There is no difference of moral principle here: the difference is simply about matter of fact. It may be a great advance in knowledge not to believe in witches: there is no moral advance in not executing them when you do not think they are there. You would not call a man humane for ceasing to set mousetraps if he did so because he believed there were no mice in the house.

-C.S. Lewis

Perfecting oneself is as much unlearning as it is learning.

Moral language persuades best when opinions are not yet formed, which is why writers of children’s literature can get away with saying things like, “Mr. Billings was an awful, horrible man with a heart of stone.” This sounds like a line from a children’s book because it employs persuasive methods that, though appropriate for children, would insult the intelligence of most adult readers.

Most moral discourse is the conversational equivalent of children’s literature. Disputants speak to one another—or, rather, at one another—as if their interlocutors failed to pay adequate attention on the day elementary morality was explained. Unaware of the projective nature of value, they marvel at their opponents’ blindness, their utter failure to see what is so perfectly obvious. Not knowing what else to do, they scold their opponents as if they were children, and scold them as if they were belligerent children when they fail to respond the first time.

What to do about this? Take a cue from good writers. Stick to the facts. Keep evaluative language to a minimum, and get rid of the most overtly judgmental, moralistic language.

A great many years ago, a couple of Jehovah Witnesses bit off more than they could chew with my grandmother. During the unsolicited conversation one of them remarked, "Only God can make a rainbow". To which my grandmother-who was watering her plants at the time-said, "Nonsense!", and created her own rainbow with a spray of water from the hose. Family lore has it that was the end of the conversation.

Yes, because to be treated as a boy was to be taken on the old footing. I had become a new person ; and those who knew the old person laughed at me. The only man who behaved sensibly was my tailor : he took my measure anew every time he saw me, whilst all the rest went on with their old measurements and expected them to fit me.

Nullius in verba ~The Royal Society

MY mistress’ eyes are nothing like the sun
Coral is far more red than her lips’ red:
If snow be white, why then her breasts are dun;
If hairs be wires, black wires grow on her head.
I have seen roses damask’d, red and white,
But no such roses see I in her cheeks;
And in some perfumes is there more delight
Than in the breath that from my mistress reeks.
I love to hear her speak, yet well I know
That music hath a far more pleasing sound:
I grant I never saw a goddess go,—
My mistress, when she walks, treads on the ground:
And yet, by heaven, I think my love as rare
As any she belied with false compare.

I find it curious that the quotes posted here have higher votes on average than the usual discussion comments, and it makes me think that I have a below-average appreciation for quotations. Why do people value them, I wonder?

When I became convinced that the Universe is natural — that all the ghosts and gods are myths, there entered into my brain, into my soul, into every drop of my blood, the sense, the feeling, the joy of freedom. The walls of my prison crumbled and fell, the dungeon was flooded with light, and all the bolts, and bars, and manacles became dust. I was no longer a servant, a serf, or a slave. There was for me no master in all the wide world — not even in infinite space. I was free — free to think, to express my thoughts — free to live to my own ideal — free to live for myself and those I loved — free to use all my faculties, all my senses — free to spread imagination’s wings — free to investigate, to guess and dream and hope — free to judge and determine for myself — free to reject all ignorant and cruel creeds, all the “inspired” books that savages have produced, and all the barbarous legends of the past — free from the popes and priests — free from all the “called” and “set apart” — free from sanctified mistakes and holy lies — free from the fear of eternal pain — free from the winged monsters of the night — free from devils, ghosts, and gods. For the first time I was free. There were no prohibited places in all the realms of thought — no air, no space, where fancy could not spread her painted wings — no chains for my limbs — no lashes for my back — no fires for my flesh — no master’s frown or threat — no following another’s steps — no need to bow, or cringe, or crawl, or utter lying words. I was free. I stood erect and fearlessly, joyously, faced all worlds.

And then my heart was filled with gratitude, with thankfulness, and went out in love to all the heroes, the thinkers who gave for the liberty of hand and brain — for the freedom of labor and thought — to those who fell in the fierce fields of war, to those who died in dungeons bound with chains — to those who proudly mounted scaffold’s stairs — to those whose bones were crushed, whose flesh was scarred and torn — to those by fire consumed — to all the wise, the good, the brave of every land, whose thoughts and deeds have given freedom to the sons of men. And then I vowed to grasp the torch that they had held, and hold it high, that light might conquer darkness still.

The carting of manure had to begin earlier, so that everything would be finished before the early mowing. The far field had to be ploughed continually, so as to keep it fallow. The hay was to be got in, not on half shares with the peasants, but by hired workers.

The steward listened attentively and obviously made an effort to approve of the master's suggestions; but all the same he had that hopeless and glum look, so familiar to Levin and always so irritating to him. This look said: "That's all very well, but it's as God grants."

Nothing so upset Levin as this tone. But it was a tone common to all stewards, as many of them as he had employed. They all had the same attitude toward his proposals, and therefore he now no longer got angry, but became upset and felt himself still more roused to fight this somehow elemental force for which he could find no other name than "as God grants", and which was continually opposed to him.
