Quote by Hermann von Helmholtz

“As you are aware, no perceptions obtained by the senses are merely sensations impressed on our nervous systems. A peculiar intellectual activity is required to pass from a nervous sensation to the conception of an external object, which the sensation has aroused. The sensations of our nerves of sense are mere symbols indicating certain external objects, and it is usually only after considerable practice that we acquire the power of drawing correct conclusions from our sensations respecting the corresponding objects.”

“In speaking of the work of machines and of natural forces we must, of course, in this comparison eliminate anything in which activity of intelligence comes into play. The latter is also capable of the hard and intense work of thinking, which tries a man just as muscular exertion does.”

“One difference between libertarianism and socialism is that a socialist society can't tolerate groups of people practicing freedom, but a libertarian society can comfortably allow people to choose voluntary socialism. If a group of people - even a very large group - wanted to purchase land and own it in common, they would be free to do so. The libertarian legal order would require only that no one be coerced into joining or giving up his property.”
