Facility Quotes - page 3
The physicist needs a facility in looking at problems from several points of view. The exact analysis of real physical problems is usually quite complicated, and any particular physical situation may be too complicated to analyze directly by solving the differential equation. But one can still get a very good idea of the behavior of a system if one has some feel for the character of the solution in different circumstances. Ideas such as the field lines, capacitance, resistance, and inductance are, for such purposes, very useful. ... On the other hand, none of the heuristic models, such as field lines, is really adequate and accurate for all situations. There is only one precise way of presenting the laws, and that is by means of differential equations. They have the advantage of being fundamental and, so far as we know, precise. If you have learned the differential equations you can always go back to them. There is nothing to unlearn.
Richard Feynman
But, whenever a portion of this facility we may suppose even the greatest Poet to possess, there cannot be a doubt that the language which it will suggest of him, must, in liveliness and truth, fall far short of that with is uttered by men in real life, under the actual pressure of these passions, certain shadows of which the poet thus produced, or feels to be produced, in himself. However exalted a notion we would wish to cherish of the character of a Poet, it is obvious, that, while he describes and imitates passions, his situation is altogether slavish and mechanical, compared with the freedom and power of real and substantial action and suffering.
William Wordsworth
We leave the question whether a man shall be a brain or hand worker entirely to him to settle. At the end of the term of three years as a common laborer, which every man must serve, it is for him to choose, in accordance to his natural tastes, whether he will fit himself for an art or profession, or be a farmer or mechanic. If he feels that he can do better work with his brains than his muscles, he finds every facility provided for testing the reality of his supposed bent, of cultivating it, and if fit of pursuing it as his avocation. The schools of technology, of medicine, of art, of music, of histrionics, and of higher liberal learning are always open to aspirants without condition.
Edward Bellamy
My father was as well aware as anyone that Christians do not, in general, undergo the demoralizing consequences which seem inherent in such a creed, in the manner or to the extent which might have been expected from it. The same slovenliness of thought, and subjection of the reason to fears, wishes, and affections, which enable them to accept a theory involving a contradiction in terms, prevents them from perceiving the logical consequences of the theory. Such is the facility with which mankind believe at one and the same time things inconsistent with one another, and so few are those who draw from what they receive as truths, any consequences but those recommended to them by their feelings, that multitudes have held the undoubting belief in an Omnipotent Author of Hell, and have nevertheless identified that being with the best conception they were able to form of perfect goodness.
