Before proceeding to a special consideration of such type lessons, it will be well to note that the mind always applies general knowledge in the learning process. That is, the application of old knowledge to the new presentation is possible only because this knowledge has taken on a general character, or has become a general way of thinking. The tendency for every new experience, whether particular or general, to pass into a general attitude, or to become a standard for interpreting other presentations, is always present, at least after the very early impressions of infancy. When, for instance, a child observes a strange object, dog, and perceives its four feet, this idea does not remain wholly confined to the particular object, but tends to take on a general character. This consists in the fact that the characteristic perceived is vaguely thought of as a quality distinct from the dog. This quality, four-footedness, therefore, is at least in some measure recognized as a quality that may occur in other objects. In other words, it takes on a general character, and will likely be applied in interpreting the next four-footed object which comes under the child's attention. So also when an adult first meets a strange fruit, guava, he observes perhaps that it is pear-shaped, yellow-skinned, soft-pulped, of sweet taste, and aromatic flavour. All such quality ideas as pear-shaped, yellow, soft, etc., as here applied, are general ideas of quality taken on from earlier experiences. Even in interpreting the qualities of particular objects, therefore, as this rose, this machine, or this animal, we apply to its interpretation general ideas, or general forms of thought, taken on from earlier experiences.
The same fact is even more evident when the mind attempts to build up the idea of a particular object by an act of imagination. One may conceive as present, a sphere, red in colour, with smooth surface, and two feet in diameter. Now this particular object is defined through the qualities spherical, red, smooth, etc. But these notions of quality are all general, although here applied to building up the image of a particular thing.
PROCESSES OF ACQUIRING KNOWLEDGE SIMILAR
If what has already been noted concerning the law of universal method is correct, and if all learning is a process of building up a new experience in accordance with the law of apperception, then all of the above modes of gaining either particular or general knowledge must ultimately conform to the laws of general method. Keeping in view the fact that applied knowledge is always general in character, it will not be difficult to demonstrate that these various processes do not differ in their essential characteristics; but that any process of acquiring either particular or general knowledge conforms to the method of selection and relation, or of analysis-synthesis, as already described in our study of the learning process. To demonstrate this, however, it will be necessary to examine and illustrate the different modes of learning in the light of the principles of general method already laid down in the text.
CHAPTER XV
MODES OF LEARNING
DEVELOPMENT OF PARTICULAR KNOWLEDGE
A. LEARNING THROUGH THE SENSES
In many lessons in nature study, elementary science, etc., pupils are led to acquire new knowledge by having placed before them some particular object which they may examine through the senses. The knowledge thus gained through the direct observation of some individual thing, since it is primarily knowledge about a particular individual, is to be classified as particular knowledge. As an example of the process by which a pupil may gain particular knowledge through the senses, a nature lesson may be taken in which he would, by actual observation, become acquainted with one of the constellations, say the Great Dipper. Here the learner first receives through his senses certain impressions of colour and form. Next he proceeds to read into these impressions definite meanings, as stars, four, corners, bowl, three, curve, handle, etc. In such a process of acquiring knowledge about a particular thing, it is to be noted that the acquisition depends upon two important conditions:
