Focal point

“ Sometimes focus and margin change places. Sometimes, again, abrupt alterations of the whole field occur. There can seldom be a sharp description. All we know is that, for the most part, each field has a sort of practical unity for its possessor, and that from this practical point of view we can class a field with other fields similar to it, by calling it a state of emotion, of perplexity, of sensation, of abstract thought, of volition, and the like. ”

“ Outward in every direction reaches the broad earth, a crowded pageantry of color and form and sound and stir. Just at the center, the meeting point of all these energies, stands a man, thinking, feeling, willing. Upon him as a focus converge all rays of influence from the inclosing world. ”

“ We know that the point of sight is the eye of the spectator; and if you ask, how is a series of subjects, such as the life of a saint, to be represented, in different compartments on the same wall? I answer, that you are to place the principal event in the largest compartment, and make the point of sight as high as the eye of the spectator. ”

“ When one proposes to enter for any purpose or from any point of view, a large field, especially a field that has already been much explored, he feels that he must hasten to define his bounds, to stake out his particular claim. ”

“ The young student is the spectator on the other side of it, the dotted lines drawn from the corners of the cube to the eye of the spectator are the visual rays, and the points on the transparent picture plane where these visual rays pass through it indicate the perspective position 8 of those points on the picture. To find these points is the main object or duty of linear perspective.

Perspective up to a certain point is a pure science, not depending upon the accidents of vision, but upon the exact laws of reasoning. ”

“ In addition to the private spaces belonging to the private worlds of different percipients, there is, however, another space, in which one whole private world counts as a point, or at least as a spatial unit. ”

“ The marginal character of an experience is simply a reference to its function as a clue or cue to some further experience, i.e., a reference to its character as a changing stimulus. Or we may say that the distinction between focus and margin is just another aspect of the distinction between the conditions for further activity and the incompleteness which leads to further adjustment. The transfer of the future into the present gives us a fact, here and now, and in this respect the experience is entirely focal in character, and as such it is subject-matter for the various sciences. ”

“ We represent the different sciences by radiating lines, [leaving / a partir] from a central point, growing further in every direction, dividing the expanse into contiguous sectors, with no interruptions or empty space. ”

“ If focalization [Pg 367] of brain-activity be the fundamental fact of reasonable thought, we see why intense interest or concentrated passion makes us think so much more truly and profoundly. The persistent focalization of motion in certain tracts is the cerebral fact corresponding to the persistent domination in consciousness of the important feature of the subject. When not 'focalized,' we are scatter-brained; but when thoroughly impassioned, we never wander from the point. ”

“ To isolate the various elements out of the synthetized percept, the central elements must be shifted,―the subordinate elements must be made focal, giving rise to new percepts, but at the same time making it possible to pass in review the various elements. ”

“ As the centre of a circle is not the point which shows the distance of one part from another but really that focus from which proceed the countless lines comprised within and constituting the complete circuit so the Lord is the centre as well as the circumference of the full circle of life. The Lord in His sanctified Self is present in the inner soul, aye, seated in the very heart of every created being. ”

“ I am forced to think that the visual field in particular is a thoroughly vicious metaphor when employed to body forth the distinction of focus and margin. Whatever this distinction may in the end turn out to be, it is not such as this comparison would lead one to suppose. Objects seen in indirect vision appear obscure and blurred precisely because they are in the focus of consciousness. ”

“ Thus in a plot the beginning stands out as setting the problem and introducing the characters and situation; then the movement of the action, gathering force increasingly as it proceeds, breaks at some point well beyond the middle; in the last part the problem is solved and the consequences of the action are revealed. Large size is another quality which distinguishes and tends to make dominant, as in the tower and the mountain. ”

“ When you are to examine the landscape from a height, in order to obtain a wide prospect, you may have to use a glass, or a compass, or some other instrument of abstraction, in order to define what the distance tends to render obscure, or what the manifoldness of the scenery surveyed makes it hard rightly to view in its true relations. And, in such cases, the glass or the compass is but an auxiliary, intended to help in the end your whole outlook. Now the world of good and evil is a world of wide prospects, of vast distances, of manifold features. ”

“ Developing a large area means the making of a picture that, year in and year out, is to be before our eyes, and unless [Pg 9] there is a most harmonious relation of all accessories—trees, contours, vistas, roads, and so on—there is sure to come a time of wearying monotony, caused by a realization of the fact that we had not been quite equal, through our lack of experience, to develop the place as it might have been developed. ”

“ In ascertaining just where the center is, in any case, we depend upon visual sensitiveness or visual feeling, guided by an understanding of the principle of balance: that equal attractions, tensions or pulls, balance at equal distances from a given center, that unequal attractions balance at distances inversely proportional to them. Given certain attractions, to find the center, we weigh the attractions together in the field of vision and observe the position of the center. ”

“ Since we can see the relative position of things, we can see figure, which is but the relative position of the different parts of the boundary of the object. And thus the whole visible world exhibits to us a scene of various shapes, coloured and shaded according to their form and position, but each having relations of position to all the rest; and altogether, entirely filling up the whole range which the eye can command. ”

“ The science of perspective gives the dimensions of objects seen in space as they appear to the eye of the spectator, just as a perfect tracing of those objects on a sheet of glass placed vertically between him and them would do ”

“ Our studies of character, to change the image, are very much like the surveyor's triangulation of a geographical province. We get a base-line in organization, always; then we get an angle by sighting some distant object to which the passions or aspirations of the subject of our observation are tending ”

“ Is not the one the appropriate field and province of observation,—a power habitually awake to all the perceptions and impressions of the bodily organs? and does not the other fall exclusively under the cognizance of reflection,—an operation which inverts all the ordinary habits of the understanding, abstracting the thoughts from every sensible object, and even striving to abstract them from every sensible image? ”

“ When the zone of our mentality is kept unclouded between our material, bodily form and that within us up at the point of the sector [Here is a diagram of a circle with an X in the center, and a sector drawn through it at the lower left.] which thinks, we are, as will be seen, in unbroken communication with the Great Thinker, God, who is Himself all in all: for our thinking self is part of Him. The application of this conception, from Mrs. ”

“ An examination of the portraits of a hundred great generals, pioneers, builders, engineers, explorers, athletes, automobile racers, aëronauts, and others who lead a life of great activity will show a general tendency toward structure on the lines of the square—square face, square body, square hands. Reference to the portraits of great judges, financiers, organizers, and commercial kings will show a general tendency toward structure upon the lines of the circle—round face, rounded body and a tendency to roundness in hands and limbs. ”

“ We have seen that we can assign to a physical thing a place in the perspective space. In this way different parts of our body acquire positions in perspective space, and therefore there is a meaning (whether true or false need not much concern us) in saying that the perspective to which our sense-data belong is inside our head. Since our mind is correlated with the perspective to which our sense-data belong, we may regard this perspective as being the position of our mind in perspective space. ”

“ In any circle, the nearer the points of the circumference are to the centre, the closer they will necessarily be to one another. As we draw nearer, each for himself, to our Centre, we shall feel that we have approximated to all those who stand round the same centre, and draw from it the same life. ”

“ So far from one all-embracing space being given, there are several spaces for each person, according to the different senses which give relations that may be called spatial. Experience teaches us to obtain one space from these by correlation, and experience, together with instinctive theorising, teaches us to correlate our spaces with those which we believe to exist in the sensible worlds of other people. ”

“ All the little bodies whirl around a common centre, but that centre is no solitary orb. It is two suns, self-luminous, revolving around each other, and neither able to throw upon its mate the burden of its shining. ”

“ Studies, for instance, made with a view to arrangements of line only—to get the characteristic and beautiful lines of a figure, a momentary attitude, the lines of a flower, or a landscape: studies with a view, solely, to the understanding of structure and form, or again, with the object of seizing the broad relations of light and shade, or tone and colour—all are necessary to a complete artistic education of the eye. ”

“ No matter what the field of view means, he sees it also as it feels—that is, as a collection of patches of color bounded by lines—the whole forming an optical diagram of whose intrinsic proportions one who is not an artist has hardly a conscious inkling. ”

“ As the objective is of short focus, every object situated beyond a distance of three yards from the apparatus is in focus. In exceptional cases, where the operator might be nearer the object to be photographed, the focusing would be done by means of the rack of the objective. ”

“ Position, for example, can never be a sensation, for it has nothing intrinsic about it; it can only obtain between a spot, line, or other figure and extraneous co-ordinates, and can never be an element of the sensible datum, the line or the spot, in itself. Let us then confess that Thought alone can unlock the riddle of space, and that Thought is an adorable but unfathomable mystery. ”

“ An illustration will make this plain: let us suppose the centre of a circle to be endowed with consciousness, and suppose we affirm that this centre can have no cognizance of the circumference, without being cognizant of itself (the centre) as well. ”

“ It is obvious, that if each eye spreads before us the same visible scene, with the same objects and the same relations of place, then, if one object in each scene coincide, the whole of the two visible impressions will be coincident. And here the remarkable circumstance is, that not only each eye judges for itself of the relations of position which come within its field of view; but that there is a superior and more comprehensive faculty which combines and compares the two fields of view ”

“ Position.—The sight has this peculiar prerogative, that it apprehends the place of its objects directly and primarily. We see where an object is at the same instant that we see what it is. If we see two objects, we see their relative position. We cannot help 303 perceiving that one is above or below, to the right or to the left of the other, if we perceive them at all. ”

“ Generally speaking, the onlooker, with his wider field of vision, regards the ultimate outcome of an activity as what it is more really doing; and the most previous agent ascertainable, being the first source of action, he regards as the most real agent in the field. ”

“ A scale might be formed, graduated according to the degrees of a combined ratio of intensity, duration, connexion, periods of recurrence, and utility, which would be the standard, according to which all ideas might be measured, and an uninterrupted chain of nicely shadowed distinctions would be observed, from the faintest impression on the senses, to the most distinct combination of those impressions; from the simplest of those combinations, to that mass of knowledge which, including our own nature, constitutes what we call the universe. ”

“ This process of striving to seize some connecting link, or thread of order, is illustrated whenever, in waking life, we are suddenly brought face to face with an unfamiliar scene. When taken into a factory, we strive to arrange the bewildering chaos of visual impressions under some scheme, by help of which we are said to understand the scene. ”

“ But this modification of distance we call place, being made by men for their common use, that by it they might be able to design the particular position of things, where they had occasion for such designation ; men consider and determine of this place by reference to those adjacent things which best served to their present purpose, without considering other things which, to another purpose, would better determine the place of the same thing. ”
