Idiosyncratic paragraphs Text-only paragraphs differ from one another only in their words. All the words are typographically the same – typeface, spacings, line-lengths piled up into long deep columns. Systematic regularity of text paragraphs is universally inconvenient for readers, who are unable to find and read once against a specific string of words in previously-read paragraphs. All readers have encountered this problem in essays, articles, novels, news reports. Idiosyncratic paragraphs assist memory and retrieval by readers, by uniquely activating the relevant neural substrates for retaining visual memories. Nearly every paragraph in this book is deliberately unique. Edward Tufte, Seeing With Fresh Eyes variation
Seven lamps Ruskin's Seven Lamps of Architecture provided seven guides, or 'lamps', for the troubled craftsman, guides for anyone who works directly on material things. These seven are: The lamp of sacrifice: The willingness to do something well for its own sake. The lamp of truth: The truth that 'breaks and rents continually'; Ruskin's embrace of difficulty, resistance, and ambiguity. The lamp of power: Tempered power, guided standards other than blind will. The lamp of beauty: Which for Ruskin is found more in the detail, the ornament—hand-sized beauty—than in the large design. The lamp of life: Life equating with struggle and energy, death with deadly perfection. The lamp of memory: The guidance provided by the time before machinery ruled. The lamp of obedience: Obedience to the example set by a master's practice rather than by his particular works; otherwise put, strive to be like Stradivari but do not seek to copy his particular violins.
