Philosophy, which once seemed outmoded, remains alive because the moment of its realization was missed. The summary judgement that it had merely interpreted the world is itself crippled by resignation before reality, and becomes a defeatism of reason after the transformation of the world failed. It guarantees no place from which theory as such could be concretely convicted of the anachronism, which then as now it is suspected of. Perhaps the interpretation which promised the transition did not suffice. The moment on which the critique of theory depended is not to be prolonged theoretically. Praxis, delayed for the foreseeable future, is no longer the court of appeals against self-satisfied speculation, but for the most part the pretext under which executives strangulate that critical thought as idle which a transforming praxis most needs. After philosophy broke with the promise that it would be one with reality or at least struck just before the hour of its production, it has been compelled to ruthlessly criticize itself.

?questioning the existence of God may begin because of one's sense of disappointment rather than because of a line of reasoning. Disappointment can bring disillusionment, and disillusionment can get quite a grip on us. It may be the case that, next to the grip of disillusionment, whatever reasons we can think of to believe that God exists or that God is good will appear weak. So sometimes the reason we do not believe or the reason we stop believing is not the intellectual challenge to believing in God. Sometimes, the grip of disillusionment cannot be matched by things that seem to be only abstract or theoretical.

We must draw up a plan for the formation of such a corps with several million people taking up the study of dialectical materialism and historical materialism, the theoretical basis of Marxism, and combating all shades of idealism and mechanical materialism. At present there are many cadres doing theoretical work, but there is still no corps of theoretical workers, much less a powerful one. Without such a corps, the cause of the entire Party, the socialist industrialization and socialist transformation of our country, the modernization of our national defence and our research in atomic energy cannot move along or succeed. I therefore recommend that you comrades read philosophy.

Metaphysics means nothing but an unusually obstinate effort to think clearly. The fundamental conceptions of psychology are practically very clear to us, but theoretically they are very confused, and one easily makes the obscurest assumptions in this science without realizing, until challenged, what internal difficulties they involve.

Being established in my life, buttressed by my thinking nature, fastened down in this transcendental field which was opened for me by my first perception, and in which all absence is merely the obverse of a presence, all silence a modality of the being of sound, I enjoy a sort of ubiquity and theoretical eternity, I feel destined to move in a flow of endless life, neither the beginning nor the end of which I can experience in thought, since it is my living self who think of them, and since thus my life always precedes and survives itself.

From it genesis twelve hundred years ago to today, Islamic philosophy (al-hikmah; al-falsafah) has been one of the major intellectual traditions within the Islamic world, and it has influenced and been influenced by many other intellectual perspectives, including Scholastic theology (kalam) and doctrinal Sufism (al-ma'rifah or al-tasawwuf al-'ilmi) and theoretical gnosis ('irfan-i nazari).

If the highest things are unknowable then the highest capacity or virtue of man cannot be theoretical wisdom.

As a theoretical physicist I feel at once proud and humble at the thought of the illustrious figures that have preceded me here to receive the greatest of all honors in science the Nobel prize.

Whenever anyone says 'theoretically ' they really mean 'not really.'

Although they can do it all the time you know they're far better than me on a musically on a theoretical music level. You know they're out of my league.

Close contact between science and the practice of collective farms and State farms creates inexhaustible opportunities for the development of theoretical knowledge enabling us to learn ever more and more about the nature of living bodies and the soil.

A theoretical grounding in agronomy must therefore include knowledge of biological laws.

Each department of knowledge passes through three stages. The theoretic stage the theological stage and the metaphysical or abstract stage.

It is that of increasing knowledge of empirical fact intimately combined with changing interpretations of this body of fact - hence changing general statements about it - and not least a changing a structure of the theoretical system.

It is probably safe to say that all the changes of factual knowledge which have led to the relativity theory resulting in a very great theoretical development are completely trivial from any point of view except their relevance to the structure of a theoretical system.

The theoretical understanding of the world which is the aim of philosophy is not a matter of great practical importance to animals or to savages or even to most civilised men.

Faith means belief in something concerning which doubt is theoretically possible.

There is the expression of selfishness and there is the expression of selflessness - but economists or theoreticians never touched that part. They said: 'Go and become a philanthropist.' I said 'No I can do that in the business world create a different kind of business - a business based on selflessness.'

Now I'm not saying I'm fashionable but there are sociological interests that matter to me things that are theoretical political intellectual and also concerned with vanity and beauty that we all think about but that I try to mix up and translate into fashion.
