Opinions

“A thousand reasoned opinions are never equal to one case of diving in and finding out. Galileo proved that.”

Brain Atoms

“The average human brain, for example, contains about a thousand trillion trillion atoms. [About 1027]. Even with today’s most powerful supercomputers, no one can calculate just how all these atoms interact to create conscious thought.”

Thomas_Robert_Malthus

Population and Subsistence

“I think I may fairly make two postulata. First, That food is necessary to the existence of man. Secondly, That the passion between the sexes is necessary, and will remain nearly in its present state... Assuming then my postulata as granted, I say, that the power of population is indefinitely greater than the power in the earth to produce subsistence for man. Population, when unchecked, increases in a geometrical ratio. Subsistence increases only in an arithmetical ratio... This implies a strong and constantly operating check on population from the difficulty of subsistence. This difficulty must fall somewhere; and must necessarily be severely felt by a large portion of mankind... The germs of existence contained in this spot of earth, with ample food, and ample room to expand in, would fill millions of worlds in the course of a few thousand years... Consequently, if the premises are just, the argument is conclusive against the perfectibility of the mass of mankind.”

Condorcet and Other Writers”. Originally published: 1798. Edition: First. Publisher: J. Johnson. Location: London, England. Chapter: 1.

  • Notes: The dire predictions of Malthus have not yet been fulfilled. This is primarily due to errors in his initial assumptions (which are properly identified), not in errors in his logic. The first assumption (or postulatum) is that food production increases arithmetically (linearly). But historically, food production has increased geometrically (exponentially) due to advances in mechanical technologies and biotechnologies. The second assumption assumes passion and birth rates are directly correlated. However, technological advances in birth control, cultural advances in women's rights, and rising prosperity (which lowers birth rates) have falsified this assumption. Additional questionable assumptions are also made which are not initially specified.

Programmers Perfectionists

“A single error in a program thousands of lines long prevented it from running correctly, and computer programmers became known as a fanatically exact group of perfectionists, working in an arcane specialty. Sociologists studying the ‘man-machine' interface found that a programmer's personality often changed after prolonged exposure to the computer, becoming severely logical and machine-like.”

Scientific Method Elucidation

“Almost every major systematic error which has deluded men for thousands of years relied on practical experience. Horoscopes, incantations, oracles, magic, witchcraft, the cures of witch doctors and of medical practitioners before the advent of modern medicine, were all firmly established through the centuries in the eyes of the public by their supposed practical successes. The scientific method was devised precisely for the purpose of elucidating the nature of things under more carefully controlled conditions and by more rigorous criteria than are present in the situations created by practical problems.”
