“Moreover, it must be confessed that perception and that which depends upon it are inexplicable on mechanical grounds, that is to say, by means of figures and motions. And supposing there were a machine, so constructed as to think, feel, and have perception, it might be conceived as increased in size, while keeping the same proportions, so that one might go into it as into a mill. That being so, we should, on examining its interior, find only parts which work one upon another, and never anything by which to explain a perception. Thus it is in a simple substance, and not in a compound or in a machine, that perception must be sought for.”

“The new architecture has 'opened' the walls so that the separateness of interior and exterior is suppressed. Walls no longer sustain since the system of construction is based upon the use of columns. This results in a new type of ground plan, an open ground plan, which is totally different from classical ones, since interior space and exterior space are interrelated.”

Theo van Doesburg (1883–1931) Dutch architect, painter, draughtsman and writer

Quote from Van Doesburg's unpublished writing, 'Fundamental principles', 1930; as cited in Theo van Doesburg, Joost Baljeu, Studio Vista, London 1974, p. 203
1926 – 1931

“If the material world rests upon a similar ideal world, this ideal world must rest upon some other; and so on, without end. It were better, therefore, never to look beyond the present material world. By supposing it to contain the principle of its order within itself, we really assert it to be God; and the sooner we arrive at that Divine Being, so much the better. When you go one step beyond the mundane system, you only excite an inquisitive humour which it is impossible ever to satisfy.”

In the meantime, this little is something which mathematics indispensably requires in its application to natural science, which, inasmuch as it must here necessarily borrow from metaphysics, need not be ashamed to allow itself to be seen in company with the latter.

“All existing things upon this earth, which have knowledge of their own existence, possess, some in one degree and some in another, the power of thought, accompanied by perception, which is the awakening of thought by the effects of external objects upon the senses.”

“Has, then, the influence of the crown increased since the Revolution? Down to the period of 1782 I believe the fact will not be much disputed. It was upon the notoriety of the fact, and the bad consequences it had produced, that the motions of the right hon. gentleman in favour of reform were founded. That it has increased, I think every impartial man must be compelled to admit…If, then, while the influence of the crown has so manifestly advanced, while the cause of liberty has remained the same, or has sustained a diminution of its strength, can it be said that we are standing upon the establishment of the Revolution, and adhering to the principles which it ascertained? It is, then, upon this ground of experience and the evidence of facts, upon proof of positive inconvenience and real declination from its original purity, that I should propose to recall our constitution to its true principles and to amend the system of our representation.”

“But it is a fallacy, if one is examining the methods by which security can be attained, to start upon the assumption, as so many hon. Members do, that we get security by an increase of air armaments or an increase of any other form of armaments.”

“Newton… (after having remarked that geometry only requires two of the mechanical actions which it postulates, namely, to describe a straight line and a circle) says: geometry is proud of being able to achieve so much while taking so little from extraneous sources. One might say of metaphysics, on the other hand: it stands astonished, that with so much offered it by pure mathematics it can effect so little. In the meantime, this little is something which mathematics indispensably requires in its application to natural science, which, inasmuch as it must here necessarily borrow from metaphysics, need not be ashamed to allow itself to be seen in company with the latter.”

Immanuel Kant (1724–1804) German philosopher

Preface, Tr. Bax (1883) citing Isaac Newton's Principia
(1786)

“Is it my role as an artist to say something, to express, to be expressive? I think it’s my role as an artist to bring to expression; it’s not my role to be expressive. I’ve got nothing particular to say, I don’t have any message to give anyone. But it is my role to bring to expression, let’s say, to define means that allow phenomenological and other perceptions, which one might use, one might work with, and then move towards a poetic existence.”

“If once we go upon niceties of construction, we shall not know where to stop. For one nicety is made a foundation for another; and that other for a third; and so on, without end.”

Rex v. Inhabitants of Caverswall (1758), Burrow (Settlement Cases), 465.

“I do not think anyone would question my sincerity when I say that there is hardly anything I would not sacrifice for peace, but there is one thing which I must except and that is the liberty which we have enjoyed for hundreds of years and which we will never surrender…No greater mistake could be made than to suppose that, because it believes war to be a senseless and cruel thing, this nation has so lost its fibre that it will not take part to the utmost of its power in resisting such a challenge if it were ever made.”

Neville Chamberlain (1869–1940) Former Prime Minister of the United Kingdom
