Aristotle Categorized Species as Immutable, the Theory of...

Aristotle noted three characteristics of his concept of species. First, each species is a whole. It is comprehensive, representative of all the objects embraced within it, and any one of these objects may be used as an example of all others. The species tree, for example, embraces all trees whether they are used for timber or for firewood; and any given tree may exemplify the species which includes all trees. Second, any one species comprises objects which have common or identical elements o...

 Aristotle Considered Experiential Knowledge of Lower Value

Aristotle gave the name experience to change which is irregular, and differentiated this from scientific knowledge, or rational knowledge. The only changes that could come within the scope of science were those which moved in the direction of, and which were governed by, final cause——the chick and the oak, again. Typical of the things which Aristotle regarded as certain, and therefore admissible to the realm of science, were the stars of the heavens which could be counted and which moved ...

 How Descartes Broke With Classical Thinking

Classical thinking had assigned different natures to different things—minerals had one nature, stars another, plants another. But Descartes discarded these distinctions and looked upon all things as being equal in nature. The mystical distinction among the natures of things thus disappeared. For example, respiration in the human body and the circulation of blood were no longer inexplicable, or virtually magic phenomena; both could now be treated in terms of extension and motion. The circula...

 Cartesian Methodology Applied to Personal Intellectual Gr...

...Cartesian methodology calls for intellectual individualism; it emphasizes reason as the common possession of all men. The reason that people disagree is that their reason has been perverted by the wrong kind of education, or poisoned by superstition, or vitiated by preoccupation. Descartes held that all men had equal and natural ability to make sound judgments, and to distinguish the true from the false, until and unless these abilities were crippled or stunted by improper education or by ...

 Bacon's Inductive Method

Bacon s adaptation of traditional methods was to begin with observation of discrete facts, and then from observed similarities in many separate events, to arrive at generalizations—and thus he formulated his inductive method. This method ofinduction enabled him to derive rational generalizations from his observations of disparate facts. Bacon's method was influential in the development of modern science, which was already in the process of development during his life-time. Bacon did not di...

 Locke Divided Experience into Sensation and Reflection

In his exploration into the nature of belief, seen from the psychological point of view Locke divided experience into two categories—first, sensation, or perception of external objects, and second, reflection, the activity in which the self observes its own state of mind, its own feelings and thoughts. According to Locke all human experience is embraced in these two categories; but the second, reflection, is based in and arises from the first, sensation. Sense impression of the external wor...

 Locke Rejected Innate Ideas as a Defense of Arbitrary Aut...

The first target against which he directed his criticism was the doctrine of innate ideas. Since Locke s position was that all knowledge is derived ultimately from experience, it was altogether natural that he should repudiate this Platonic doctrine; but there was another reason for his determination to discredit it. The doctrine of innate ideas had become a weapon for the defense of arbitrary authority, of superstition, and of ridiculous theories. Men in authority argued that their actions w...

 Locke's Philosophical Criticism Destroyed the Institution...

We must note two aspects of Locke’s method of analysis. One is that it was primarily a method of criticism, a method which by means of analysis subjected to critical scrutiny the many complex ideas which prevail in a society, and which because of their abstruse nature, cause confusion and misunderstanding. Locke proposed that all such ideas be analyzed into their simple components and examined critically so that the degree of their validity might be determined. The other aspect for us to no...

 Observation Provides Data on Problems, but Cannot Solve Them

A good illustration of the scientific method, in which observations are made for the purpose of identifying difficulties and analyzing situations, is the procedure followed by a physician when he makes a diagnosis. A doctor does not write a prescription solely on the basis of what his patient tells him; he uses instruments to take the patient’s temperature to examine his feces, and to analyze his urine. It is only after he has made these examinations that he writes his prescription; without...

 The Scientific Method is a Process for Knowing that is Su...

Since mere observation cannot provide the solution to a problem, no matter how accurately it is conducted the necessary next step is inference the process which leads from the present to the future, from the known to the unknown. Every inference is a sort of adventure. Another difference between the scientific method and ordinary common sense is that the former controls the adventure more carefully, and thus reduces the danger involved. The more rigorous the method the less the danger. Safegu...

 The Scientific Process Encompasses Numerous Viewpoints

We can get rid of outdated ways of looking at things, of fixed experience, of ingrained intellectual habits, only by constantly expanding our experience and continually comparing one idea with another in order to select the better one. Because systematic science is the result of constant comparison of innumerable materials and experiences, it cannot be produced by individual effort; it is a social product. Science has no nationality; it admits no prejudices. Scientific discoveries made in one...

 The Scientific Method Produces General Principles by Whic...

Just as the first means by which science reduces the danger of error is the continual comparison of ideas and concepts, the second is the formulation of general principles by means of which we can understand cause-and-effect or sequential relationships among events. The function of a general principle or scientific law is twofold; to organize discrete objects and events in systematic order so that we can deal with them more effectively and exercise greater control over them; and to provide a ...

 How Scientific Experimentation is Superior to Rationality...

Now that we have looked at the differences between the experimental type of thinking and the other types we have discussed, we can see that it is superior to any of the others. Experimental thinking does, to be sure, emphasize systematization and classification, but as means, not as ends in themselves. And, along with rationalism, it emphasizes general principles and laws, but again, not as ends in themselves, but as convenient guides for making our inferences. Neither observation nor infere...
