The collective matrix of a science at a given time is determined by a kind of establishment, which includes universities, learned societies, and, more recently, the editorial offices of technical journals. Like other establishments, they are consciously or unconsciously bent on preserving the status quo- partly because unorthodox innovations are a threat to their authority, but also because of the deeper fear that their laboriously erected an intellectual edifice might collapse under the impact.

...the cosmology of a given age is not the result of unilinear, "scientific" development, but rather the most striking, imaginative symbol of its mentality- the projection of its conflicts, prejudice and specific ways of double-think onto the graceful sky.

The 'missing link' between ape and man will probably never be found- because it was an embryo.

Modern man lives isolated in his artificial environment, not because the artificial is evil as such, but because of his lack of comprehension of the forces which make it work- of the principles which relate his gadgets to the forces of nature, to the universal order. It is not central heating which makes his existence 'unnatural,' but his refusal to take an interest in the principles behind it. By being entirely dependent on science, yet closing his mind to it, he leads the life of an urban barbarian.

The process of evolution may be described as differentiation of structure and integration of function. The more differentiated and specialized the parts, the more elaborate co-ordination is needed to create a well-balanced whole. The ultimate criterion of the value of a functional whole is the degree of its internal harmony or integratedness, whether the "functional whole" is a biological species or a civilization or an individual. A whole is defined by the pattern of relations between its parts, not by the sum of its parts; and a civilization is not defined by the sum of its science, technology, art and social organization, but by the total pattern which they form, and the degree of harmonious integration in that pattern.

...one of the tests of a theory is that, once grasped, it appears self-evident.
