# „Neither the circle without the line, nor the line without the point, can be artificially produced. It is, therefore, by virtue of the point and the Monad that all things commence to emerge in principle. That which is affected at the periphery, however large it may be, cannot in any way lack the support of the central point.“

—  John Dee, Monas Hieroglyphica (1564), Theorem II
1527 - 1608

### „Every measurable thing except numbers is imagined in the manner of a continuous quantity. Therefore, for the mensuration of such a thing, it is necessary that points, lines, and surfaces, or their properties, be imagined. For in them… measure or ratio is initially found… Therefore, every intensity which can be acquired successively ought to be imagined by a straight line perpendicularly erected on some point of the space or subject of the intensible thing, e. g., a quality… And since the quantity or ratio of lines is better known and is more readily conceived by us—nay the line is in the first species of continua, therefore such intensity ought to be imagined by lines… Therefore, equal intensities are designated by equal lines, a double intensity by a double line, and always in the same way if one proceeds proportionally.“

Tractatus de Configurationibus et Qualitatibus et Motuum (c. 1350)

### „How could one argue with a man who was always drawing lines and circles to explain the position; who, one day, drew a diagram [here Michael illustrated with pen and paper] saying 'take a point A, draw a straight line to point B, now three-fourths of the way up the line take a point C. The straight line AB is the road to the Republic; C is where we have got to along the road, we canot move any further along the straight road to our goal B; take a point out there, D [off the line AB]. Now if we bend the line a bit from C to D then we can bend it a little further, to another point E and if we can bend it to CE that will get us around Cathal Brugha which is what we want!“

How could you talk to a man like that?

### „A new point is determined in Euclidean Geometry exclusively in one of the three following ways:Having given four points A, B, C, D, not all incident on the same straight line, then(1) Whenever a point P exists which is incident both on (A, B) and on (C, D), that point is regarded as determinate.(2) Whenever a point P exists which is incident both on the straight line (A, B) and on the circle C(D), that point is regarded as determinate.(3) Whenever a point P exists which is incident on both the circles A(B), C(D), that point is regarded as determinate.The cardinal points of any figure determined by a Euclidean construction are always found by means of a finite number of successive applications of some or all of these rules (1), (2) and (3). Whenever one of these rules is applied it must be shown that it does not fail to determine the point. Euclid's own treatment is sometimes defective as regards this requisite.In order to make the practical constructions which correspond to these three Euclidean modes of determination, correponding to (1) the ruler is required, corresponding to (2) both ruler and compass, and corresponding to (3) the compass only.…it is possible to develop Euclidean Geometry with a more restricted set of postulations. For example it can be shewn that all Euclidean constructions can be carried out by means of (3) alone…“

### „What is line? It is life. A line must live at each point along its course in such a way that the artist’s presence makes itself felt above that of the model“

—  Jean Cocteau French poet, novelist, dramatist, designer, boxing manager and filmmaker 1889 - 1963
Context: What is line? It is life. A line must live at each point along its course in such a way that the artist’s presence makes itself felt above that of the model... With the writer, line takes precedence over form and content. It runs through the words he assembles. It strikes a continuous note unperceived by ear or eye. It is, in a way, the soul’s style, and if the line ceases to have a life of its own, if it only describes an arabesque, the soul is missing and the writing dies. "De la Ligne" in La Difficulté d’Etre [The Difficulty of Being] (1947)

### „When… we have a series of values of a quantity which continually diminish, and in such a way, that name any quantity we may, however small, all the values, after a certain value, are severally less than that quantity, then the symbol by which the values are denoted is said to diminish without limit. And if the series of values increase in succession, so that name any quantity we may, however great, all after a certain point will be greater, then the series is said to increase without limit.“

—  Augustus De Morgan British mathematician, philosopher and university teacher (1806-1871) 1806 - 1871
The Differential and Integral Calculus (1836), It is also frequently said, when a quantity diminishes without limit, that it has nothing, zero or 0, for its limit: and that when it increases without limit it has infinity or &infin; or 1&frasl;0 for its limit.

### „C being what it is lacks support for multiple return values, so the notion that it is meaningful to pass pointers to memory objects into which any random function may write random values without having a clue where they point, has not been debunked as the sheer idiocy it really is.“

### „There are no rules. However, principles may be discerned in actual practice; for example, in the way people actually speak, or in the lines the poets have written.“

### „And its seeing is Unconditioned, Being without manner, And it is neither thus nor thus, Neither here nor there; For that which is Unconditioned hath enveloped all, And the vision is made high and wide. It knows not itself where That is which it sees; and it cannot come thereto, for its seeing is in no wise, and passes on, beyond, for ever, and without return. That which it apprehends it cannot realise in full, Nor wholly attain, for its apprehension is wayless, and without manner, And therefore it is apprehended of God in a higher way than it can apprehend Him. Behold! such a following of the Way that is Wayless, Is intermediary between contemplation In images and similitudes of the intellect, And unveiled contemplation Beyond all images in the Light of God.“

### „Ultimately, the main product being sold by human potential gurus is hope itself. It should be obvious that in itself this is not a bad thing. We all need hope. Without hope, there is no point in making plans for the future. Without hope, there is no point in working on a relationship or setting goals. Thus, insofar as participation in Large Group Awareness Training increases one's hope for finding one's way and for achieving one's goals, it is good. Even false hope may be better than no hope at all.“

### „As a Line, I say, is looked upon to be the Trace of a Point moving forward, being in some sort divisible by a Point, and may be divided by Motion one Way, viz. as to Length; so Time may be conceiv'd as the Trace of a Moment continually flowing, having some Kind of Divisibility from an Instant, and from a successive Flux, inasmuch as it can be divided some how or other. And like as the Quantity of a Line consists of but one Length following the Motion; so the Quantity of Time pursues but one Succession stretched out as it were in Length, which the Length of the Space moved over shews and determines. We therefore shall always express Time by a right Line; first, indeed, taken or laid down at Pleasure, but whose Parts will exactly answer to the proportionable Parts of Time, as its Points do to the respective Instants of Time, and will aptly serve to represent them. Thus much for Time.“

### „The floorboards point in parallel lines to a vanishing point that does not concern us -- somewhere beyond the opera house, across the streets, across the houses of the suburbs, all the way to a hypothetical single dot… on the sea's horizon. Far from this sour drama.“

### „The informative phase refers to those things which authority should know in framing its decisions; the advisory, to the actual counsel based on such information; the supervisory, to both preceding phases as applied to all the details of execution. The point is that the line represents the authority of man; the staff, the authority of ideas. The staff is purely an auxiliary service. Its function is to be informative and advisory with respect to both plans and their execution. This is implicit in the word "staff" which is something to support or lean upon but without authority to decide or initiate.“
