A complete theory would have to answer, among others, the following questions, given two adjoining retinal areas of different stimulation, under what conditions will the corresponding parts of the behavioural (perceptual) field appear of different whiteness but equal brightness (or "illumination"), when of different brightness but equal whiteness? A complete answer to this question would probably supply the key to the complete theory of colour perception in the broadest sense.

The need for sociability induce man to be in touch with his fellow men. However, this need might not ("ne saurait", Fr.) find its full (or complete) satisfaction in the conventional (or superficial, - "conventionnel", Fr.) and deceitful world, in which (or where) everyone is mainly (or mostly) trying to assert oneself in front of others ("devant les autres", Fr.), to appear, and hoping to find in society ("mondaine", Fr.) relationships some advantages for his interest and vanity (or vainglory or conceit", Fr).

This is the highest honour of the Church, that, until He is united to us, the Son of God reckons himself in some measure imperfect. What consolation is it for us to learn, that, not until we are along with him, does he possess all his parts, or wish to be regarded as complete! Hence, in the First Epistle to the Corinthians, when the apostle discusses largely the metaphor of a human body, he includes under the single name of Christ the whole Church.
John Calvin
The central fact for me is, I think, that the [role of the] intellectual ... cannot be played without a sense of being someone whose place it is publicly to raise embarrassing questions, to confront orthodoxy and dogma (rather than to produce them), to be someone who cannot easily be co-opted by governments or corporations, and whose raison d'être is to represent all those people and issues that are routinely forgotten or swept under the rug.
Edward Said
Given the five parts of the organization - operating core, strategic apex, middle line, technostructure, and support staff - we may now ask how they all function together. In fact, we cannot describe the one way they function together, for research suggests that the linkages are varied and complex. The parts of the organization are joined together by different flows - of authority, of work material, of information, and of decision processes.

If we make this readjustment to view Homo sapiens as an ultimate in oddball rarity, and life at bacterial grade as the common expression of a universal phenomenon, then we could finally ask the truly fundamental question raised by the prospect of Martian fossils. If life originates as a general property of the material universe under certain conditions (probably often realized), then how much can the basic structure and constitution of life vary from place to independent place?
