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 ...

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...

 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...

 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...

 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...

 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...

 Vitamin D and Omega-3 Slow Aging

Previously in DO-HEALTH (including all 2,157 participants), we reported that omega-3 alone reduced the rate of infections by 13% (ref. 22) and the rate of falls by 10% (ref. 23), and all three interventions combined showed a significant additive benefit on reducing prefrailty by 39% (ref. 24) and incident invasive cancer by 61% (ref. 25) over a 3-year follow-up. The aim of the DNAm analysis in DO-HEALTH Bio-Age was to assess the effects of the interventions at the molecular level. Three of th...

 The World and Beliefs

The world with its quarks and chromosomes, its distant lands and spiral nebulae, is like a vast computer in a black box, forever sealed except for its input and output registers. These we directly observe, and in the light of them we speculate on the structure of the machine, the universe. Thus it is that we think up the quarks and chromosomes, the distant lands and the nebulae; they would account for the observable data. When an observation turns out unexpectedly, we may try modifying our th...

 The Personal Equation

Sounds like a "fuzzy set." Which comes into play when you try to categorize things that vary continuously into discrete groups. Can't be done without ambiguruity and bias. As a geneficist by the name of Pearl demonstrated when he had 15 scienfists sort the same 532 com kernels into yellow-starchy, yellow-sweet, white-starchy or whitesweet groupings. Each scientist came up with a different count. Instead of objectivity. Pearl discovered "personal equation," the slight nuance in perception each...

 How Our Grandparents Perceive the World as Unchanging

Men can know a thing and yet know it quite ineffectively if it contradicts the general traditions and habits in which they live. [...] ONE of the most striking differences between the outlook of our grandparents and that of a modern intelligence today is the modification of time values that has occurred. By the measure of our knowledge their time-scale was extremely shallow. They had scarcely any historical perspective at all. They looked back to a past of a few thousand years and at the v...
