The rules of navigation never navigated a ship. The rules of architecture never built a house. Thomas Reid More Quotes by Thomas Reid More Quotes From Thomas Reid There is no greater impediment to the advancement of knowledge than the ambiguity of words. Thomas Reid speech-impediment advancement ambiguity In every chain of reasoning, the evidence of the last conclusion can be no greater than that of the weakest link of the chain, whatever may be the strength of the rest. Thomas Reid lasts links may Every man feels that perception gives him an invincible belief of the existence of that which he perceives; and that this belief is not the effect of reasoning, but the immediate consequence of perception. When philosophers have wearied themselves and their readers with their speculations upon this subject, they can neither strengthen this belief, nor weaken it; nor can they shew how it is produced. It puts the philosopher and the peasant upon a level; and neither of them can give any other reason for believing his senses, than that he finds it impossible for him to do otherwise. Thomas Reid giving men believe A definition is nothing else but an explication of the meaning of a word, by words whose meaning is already known. Hence it is evident that every word cannot be defined; for the definition must consist of words; and there could be no definition, if there were not words previously understood without definition. Thomas Reid defined understood definitions The laws of nature are the rules according to which the effects are produced; but there must be a cause which operates according to these rules. The laws of navigation never navigated a ship. The rules of architecture never built a house. Thomas Reid law house science The want of faith, as well as faith itself, is best shewn by works. If a sceptic avoid the fire as much as those who believe it dangerous to go into it, we can hardly avoid thinking his scepticism to be feigned, and not real. Thomas Reid real believe thinking The finest productions of human art are immensely short of the meanest work of Nature. The nicest artist cannot make a feather or the leaf of a tree. Thomas Reid finest tree art In every case, we ought to act that part towards another, which we would judge to be right in him to act toward us, if we were in his circumstances and he in ours; or more generally - What we approve in others, that we ought to practise in like circumstances, what we condemn in others we ought not to do. Thomas Reid psychology ethics judging A philosopher is, no doubt, entitled to examine even those distinctions that are to be found in the structure of all languages... in that case, such a distinction may be imputed to a vulgar error, which ought to be corrected in philosophy. Thomas Reid errors doubt philosophy And, if we have any evidence that the wisdom which formed the plan is in the man, we have the very same evidence, that the power which executed it is in him also. Thomas Reid evidence wisdom men Every conjecture we can form with regard to the works of God has as little probability as the conjectures of a child with regard to the works of an adult. Thomas Reid adults god children [I]f a man bred to the seafaring life, and accustomed to think and talk only of matters relating to navigation, enters into discourse upon any other subject; it is well known, that the language and the notions proper to his own profession are infused into every subject, and all things are measured by the rules of navigation: and if he should take it into his head to philosophize concerning the faculties of the mind, it cannot be doubted, but he would draw his notions from the fabric of the ship, and would find in the mind, sails, masts, rudder, and compass. Thomas Reid mind men thinking Every theory in philosophy, which is built on pure conjecture, is an elephant; and every theory that is supported partly by fact, and partly by conjecture, is like Nebuchadnezzar's image, whose feet were partly of iron, and partly of clay. Thomas Reid iron elephants philosophy There is no greater impediment to the advancement of knowledge than the ambiguity of words. To this chiefly it is owing that we find sects and parties in most branches of science [and politics]; and disputes that are carried on from age to age, without being brought to issue. Thomas Reid issues party age We find sects and parties in most branches of science; and disputes which are carried on from age to age, without being brought to an issue. Sophistry has been more effectually excluded from mathematics and natural philosophy than from other sciences. In mathematics it had no place from the beginning; mathematicians having had the wisdom to define accurately the terms they use, and to lay down, as axioms, the first principles on which their reasoning is grounded. Accordingly, we find no parties among mathematicians, and hardly any disputes. Thomas Reid issues party philosophy The wisdom of God exceeds that of the wisest man, more than his wisdom exceeds that of a child. If a child were to conjecture how an army is to be formed in the day of battle--how a city is to be fortified, or a state governed--what chance has he to guess right? As little chance has the wisest man when he pretends to conjecture how the planets move in their courses, how the sea ebbs and flows, and how our minds act upon our bodies. Thomas Reid army children moving For the perception of the beautiful we have the term "taste"--a metaphor taken from that which is passive in the body and transferred to that which is active in the mind. Thomas Reid perception taken beautiful For, until the wisdom of men bear some proportion to the wisdom of God, their attempts to find out the structure of his works, by the force of their wit and genius, will be vain. Thomas Reid genius bears men Every indication of wisdom, taken from the effect, is equally an indication of power to execute what wisdom planned. Thomas Reid effects taken wisdom It is the invaluable merit of the great Basle mathematician Leonard Euler, to have freed the analytical calculus from all geometric bounds, and thus to have established analysis as an independent science, which from his time on has maintained an unchallenged leadership in the field of mathematics.
