Computer Arithmetic
“Computers are better than we are at arithmetic, not because computers are so good at it, but because we are so bad at it.”

Requirements Testing
“Requirements testing is a subtle way of treating a nonlinear, unpredictable system as if it were a discrete symbol like a number or a word. The potential and the actual become muddled. Requirements are natural language statements, peppered in places with arithmetic. These are discrete and usually quite vague representations of the system as it might become. But the truth is that two teams writing requirements for the same system would describe them differently, and neither would get it quite right, simply because 'right' cannot be known until the system is built. ... Requirements testing is a little like trying to reduce crime in England by running a test for each line in the Magna Carta. In practice, rhetoric replaces the scientific method. As with mathematical proofs, the quest for 'true or not false' soon turns into a party - a not very cordial party - marked by endless debate over whether this sentence or that sentence has been verified by this moment of behavior or that.”

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.

Persecution Used In Theology
“Persecution is used in theology, not in arithmetic, because in arithmetic there is knowledge, but in theology there is only opinion. So, whenever you find yourself getting angry about a difference of opinion, be on your guard, you will probably find, on examination, that your belief is going beyond what the evidence warrants.”

Savage Controversies
“The most savage controversies are those about matters as to which there is no good evidence either way. Persecution is used in theology, not in arithmetic.”
