The line has in itself neither matter nor substance and may rather be called an imaginary idea than a real object; and this being its nature it occupies no space. Therefore an infinite number of lines may be conceived of as intersecting each other at a point, which has no dimensions and is only of the thickness (if thickness it may be called) of one single line. (Leonardo da Vinci)

The connection is rather this: "I am richer than you, therefore my property is greater than yours;" "I am more eloquent than you, therefore my style is better than yours." But you, after all, are neither property nor style. (44). View quote

It is to be emphasized that no matter how many [amplitude] arrows we draw, add, or multiply, our objective is to calculate a single final arrow for the event. Mistakes are often made by physics students at first because they do not keep this important point in mind. They work for so long analyzing events involving a single photon that they begin to think that the arrow is somehow associated with the photon. View quote

The soul, when accustomed to superfluous things, acquires a strong habit of desiring things which are neither necessary for the preservation of the individual nor for that of the species. This desire is without limit, whilst those which are necessary are few in number and restricted within certain limits; but what is superfluous is without end... View quote

Freedoms and apprenticeships are likewise expedients of police, not of that wholesome branch of police, whose object is the maintenance of the public and private security, and which is neither costly nor vexatious; but of that sort of police which bad governments employ to preserve or extend their personal authority at any expense.

Freedom is neither a legal invention nor a philosophical conquest, the cherished possession of civilizations more valid than others because they alone have been able to create or preserve it. It is the outcome of an objective relationship between the individual and the space he occupies, between the consumer and the resources at his disposal. View quote
