It would be better, I think, for the man who really seeks the truth not to ask what the poets say; rather, he should first learn the method of finding the scientific premises that I discussed in the second book; then he should train and exercise himself in this method; and when his training is sufficiently advanced, then, as he approaches each particular problem, he should enquire into the premise needed for proving it, which premise he should take from simple sense-perception, which from experience, whether drawn from life or from the arts, which from the truths clearly apprehended by the mind, in order to draw out from them the desired conclusion.

There are many cases where landlords take advantage of the needs of municipalities and even of national needs and of the monopoly which they have got in land in a particular neighbourhood in order to demand extortionate prices. Take the very well-known case of the Duke of Northumberland, when a county council wanted to buy a small plot of land as a site for a school to train the children who in due course would become the men labouring on his property. The rent was quite an insignificant thing; his contribution to the rates I think it was on the basis of 30s. an acre. What did he demand for it for a school? £900 an acre. All we say is this-if it is worth £900, let him pay taxes on £900.

I do remember one formative influence in my undergraduate life. There was an elderly professor in my department who had been passionately keen on a particular theory for, oh, a number of years, and one day an American visiting researcher came and he completely and utterly disproved our old man's hypothesis. The old man strode to the front, shook his hand and said, "My dear fellow, I wish to thank you, I have been wrong these fifteen years". And we all clapped our hands raw. That was the scientific ideal, of somebody who had a lot invested, a lifetime almost invested in a theory, and he was rejoicing that he had been shown wrong and that scientific truth had been advanced.

There are two general Methods made use of in the Mathematicks, viz. Synthesis and Analysis, which we shall explain, after having acquainted the Reader, that the Method we make use of to resolve a Mathematical Problem, is called Zetetick; and that that Method which determines when, and by what way, and how many different ways a Problem may be resolved, is called Poristick. But in treating of Methods, we will first premise, that in general, a Method is the Art of disposing a Train of Arguments or Consequences in a right Order, either to discover the Truth of a Theorem, which we would find out, or to demonstrate it to others, when found.

Biography can be the most middle-class of all forms, the judgment of little people avenging themselves on the great. One English critic took me to task for not saying that Genet was "afraid of intimacy" all his life because he'd been abandoned by his mother at the age of seven months. All the evidence needed to make such an interpretation is in my book, but I don't myself draw the vulgar conclusion. Since most literary biographies ignore the work except for potted plot summaries, they strip the biographee of everything redeeming and leave his or her subject to this spiteful revenge, this half-baked Freudian-Christian-bourgeois moralizing.

In this book I try to show how models of self-organization can be applied to many economic phenomena - how the principle of "order from instability," which explains the growth of hurricanes and embryos, can also explain the formation of cities and business cycles; how the principle of "order from random growth" can explain the strangely simple rules that describe the sizes of earth quakes, meteorites, and metropolitan areas. I believe that the ideas of self-organization theory can add substantially to our understanding of the economy; whatever their ultimate usefulness, these ideas are very exciting, and playing around with them is tremendous fun.
