"Love and sympathy are the activity of the idea. And in their exercise, the idea is enlarged. The lover widens his experience as the non-lover cannot. He adds to the mass of his idea-world, and acquires thereby enhanced power to appreciate all things. Is not this the sufficient solution of that long-standing difficulty between 'egoism and altruism?' The altruist alone can accumulate that treasure of idea through which all things must be enjoyed that are enjoyed. No one has, or can have, any 'egoistic' satisfaction except as a consequence of so much effective love of reality as there is in him by birth or acquisition."

"Nothing can stir the "depths" of mind, but total out-of-doors. We call "depth," last dregs, etc., that in man which only ultimate facts and happenings can interest; that which the near and usual can neither rouse nor ruffle. Somewhere in each man, we imagine, there lies an ultimatum, to be backed by all his energies from all reservoirs, ordinary and extraordinary,--what can elicit from any man such ultimatum and ultimatum-backing?--nothing that has not somewhere in it the word All! There are such things, we think, as ruling passions, "deepest desires," in any man some nameable or unnameable last ambition--what can set such a depth on fire?--nothing but some total opportunity (real or believed real), discovered in the wide world beyond the self."

"However rich we may become in knowledge of the deeper causes of historical results, we forgo all understanding of history if we forget this inner continuity,--i.e., the conscious intentions of the participants in history-making and their consciously known successes."

"We are driven to confess that we actually care more for religion than we do for religious theories and ideas: and in merely making that distinction between religion and its doctrine-elements, have we not already relegated the latter to an external and subordinate position? Have we not asserted that "religion itself" has some other essence or constitution than mere idea or thought?"

"What our view of the effectiveness of religion in history does at once make evident as to its nature is--first, its necessary distinction; second, its necessary supremacy. These characters though external have been so essential to its fruitfulness, as to justify the statement that without them religion is not religion. A merged religion and a negligible or subordinate religion are no religion."

"I find that a man is as old as his work. If his work keeps him from moving forward, he will look forward with the work."

"Man is the only animal that contemplates death, and also the only animal that shows any sign of doubt of its finality. This does not mean that he doubts it as a future fact. He accepts his own death, with that of others, as inevitable; plans for it; provides for the time when he shall be out of the picture. Yet, not less today than formerly, he confronts this fact with a certain incredulity regarding the scope of its destruction."

"Although I firmly believe that there is no such thing as a stupid question, there can indeed be stupid answers. 42 is an example. Not only is this a poor ripoff of Doug Adams' Hitchhiker's Guide, but it isn't even a prime number. Everyone surely knows that numerical answers to profound questions are always prime. (The correct answer is 37.)"

"The major problems facing the development of products that are safer, less prone to error, and easier to use and understand are not technological: they are social and organizational."

"We are victims of our own success. We have let technology lead the way, pushing ever faster to newer, faster, and more powerful systems, with nary a moment to rest, contemplate, and to reflect upon why, how, and for whom all this energy has been expended."

"Go to the bookstore and look at how many bookshelves are filled with books trying to explain how to work the devices. We don't see shelves of books on how to use television sets, telephones, refrigerators or washing machines. Why should we for computer-based applications?"

"As the technology matures, it becomes less and less relevant. The technology is taken for granted. Now, new customers enter the marketplace, customers who are not captivated by technology, but who instead want reliability, convenience, no fuss or bother, and low cost."

"In the consumer economy taste is not the criterion in the marketing of expensive soft drinks, usability is not the primary criterion in the marketing of home and office appliances. We are surrounded with objects of desire, not objects of use."

"Hypertext makes a virtue out of lack of organization, allowing ideas and thoughts to be juxtaposed at will. [...] The advent of hypertext is apt to make writing much more difficult, not easier. Good writing, that is."

"When I use a direct manipulation system—whether for text editing, drawing pictures, or creating and playing games—I do think of myself not as using a computer but as doing the particular task. The computer is, in effect, invisible. The point cannot be overstressed: make the computer system invisible."

"Serious accidents are frequently blamed on "human error." Yet careful analysis of such situations shows that the design or installation of the equipment has contributed significantly to the problems. The design team or installers did not pay sufficient attention to the needs of those who would be using the equipment, so confusion or error was almost unavoidable."

"Computer scientists have so far worked on developing powerful programming languages that make it possible to solve the technical problems of computation. Little effort has gone toward devising the languages of interaction."

"Creeping featurism is a disease, fatal if not treated promptly. There are some cures, but, as usual, the best approach is to practice preventative medicine."

"Innocence lost is not easily regained. The designer simply cannot predict the problems people will have, the misinterpretations that will arise, and the errors that will get made."

"In their work, designers often become expert with the device they are designing. Users are often expert at the task they are trying to perform with the device. [...] Professional designers are usually aware of the pitfalls. But most design is not done by professional designers, it is done by engineers, programmers, and managers."

""It probably won a prize" is a disparaging remark in this book. Why? Because prizes tend to be given for some aspects of design, to the neglect of all others—usually including usability."

"Change the attitude toward errors. Think of an object's user as attempting to do a task, getting there by imperfect approximations. Don't think of the user as making errors; think of the actions as approximations of what is desired."

"Even though principles of rationality seem as often violated as followed, we still cling to the notion that human thought should be rational, logical, and orderly. Much of law is based upon the concept of rational thought and behavior. Much of economic theory is based upon the model of the rational human who attempts to optimize personal benefit, utility, or comfort. Many scientists who study artificial intelligence use the mathematics of formal logic—the predicate calculus—as their major tool to simulate thought. [...] Human thought is not like logic; it is fundamentally different in kind and spirit. The difference is neither worse nor better. But it is the difference that leads to creative discovery and to great robustness of behavior."

"The principle of visibility is violated over and over again in everyday things. In numerous designs crucial parts are carefully hidden away. Handles on cabinets distract from some design aesthetics, and so they are deliberately made invisible or left out. The cracks that signify the existence of a door can also distract from the pure lines of the design, so these significant cues are also minimized or eliminated. The result can be a smooth expanse of gleaming material, with no sign of doors or drawers, let alone of how those doors and drawers might be operated."

"When a device as simple as a door has to come with an instruction manual—even a one-word manual—then it is a failure, poorly designed."

"Usability is not often thought of as a criterion during the purchasing process. Moreover, unless you actually test a number of units in a realistic environment doing typical tasks, you are not likely to notice the ease or difficulty of use. [...] Do it right there in the store. Do not be afraid to make mistakes or ask stupid questions. Remember, any problems you have are probably the design's fault, not yours."

"If people keep buying poorly designed products, manufacturers and designers will think they are doing the right thing and continue as usual."

"People Propose, Science Studies, Technology Conforms."

"Academics get paid for being clever, not for being right."

"Technologists are not noted for learning from the errors of the past. They look forward, not behind, so they repeat the same problems over and over again. [...] As each new technology matures, customers are no longer happy with the flashy promises of the technology but instead demand understandable and workable designs. Slowly the manufacturers relearn the same basic principles and apply them to their products. The most egregious failures always come from the developers of the most recent technologies."

"Good design is also an act of communication between the designer and the user, except that all the communication has to come about by the appearance of the device itself. The device must explain itself."

"When you have trouble with things—whether it's figuring out whether to push or pull a door or the arbitrary vagaries of the modern computer and electronics industries—it's not your fault. Don't blame yourself: blame the designer."

"It quickly becomes apparent to any person who has considerable experience with classified material that there is massive overclassification and that the principal concern of the classifiers is not with national security, but rather with governmental embarrassment of one sort or another."
