An impulse, symbol J, is is the product of a force F and the time t for which it acts:
An impulse, in other words, is force acting over period of time. The larger the time interval over which the force acts or operates, the greater the impulse. The greater the force in a given time interval, the greater the impulse.
The following are quotes:
- “What man, what society dare express such sentiments? Seeing that we cannot easily have known anyone from his youth up, nor criticize the rise of his activity. How else does character finally prove itself, if it is not formed by the activity of the day, by reflective agencies which counteract each other? Who would venture to determine the value of contingencies, impulses, after-effects? Who dare to estimate the influence of elective affinities? At all events, he who would presume to estimate what man is, must take into consideration what he was, and how he became so. But such barefaced pretension are common, and we have often enough met with them; indeed they are always recurring, and they must be tolerated.”
- “Man is a compound being, composed of two principles—one active, the other passive. The active principle is what is called the mind, the soul; the passive principle is the body. The latter is the material instrument of the former, the means by which it inhabits the planet, acts upon matter, and arrives at a state of positive and practical existence. The soul, or active principle in man, is a whole, composed of a certain number of forces or motors, which we shall call the passions; by the metaphysicians, these forces are variously termed—sentiments, affections, feelings, faculties, impulses, instincts. The passions are spontaneously active and self-determining forces; they are the thinking, feeling, creating principle in man — the source of his acts and works in all spheres, material and spiritual. They are the agents of supreme wisdom, the motors implanted in him by that wisdom to impel him to fulfill his destiny on earth. The human passions were not created at random, were not called into existence without functions and employments having been assigned to them; on the contrary, their functions and uses have been calculated with mathematical precision.”
- “In respect to what gave me the ‘impulse’ behind my We Human Chemicals writings, it came to me years ago, when I was loafing in my canoe out in Wisconsin, and found a verse that appealed to me. I wished then that lots of people could read it too, and then it came to me that there was a place for a magazine that would hand on bits of inspiration to people whose lives were too full for them to do much straight reading along those lines. The whole idea of the Thomas Dreier Service grew from that. Of course, a lot that I have done was influenced by Elbert Hubbard, and I am very willing to acknowledge what a power he has been in the formation of my style.”
