A Quote by Chauncey Wright

Science asks no questions about the ontological pedigree or a priori character of a theory, but is content to judge it by its performance; and it is thus that a knowledge of nature, having all the certainty which the senses are competent to inspire, has been attained--a knowledge which maintains a strict neutrality toward all philosophical systems and concerns itself not with the genesis or a priori grounds of ideas.

Natural science physics contains in itself synthetical judgments a priori, as principles. ... Space then is a necessary representation a priori, which serves for the foundation of all external intuitions.

Immanuel Kant

I am convinced that it is impossible to expound the methods of induction in a sound manner, without resting them upon the theory of probability. Perfect knowledge alone can give certainty, and in nature perfect knowledge would be infinite knowledge, which is clearly beyond our capacities. We have, therefore, to content ourselves with partial knowledge - knowledge mingled with ignorance, producing doubt.

William Stanley Jevons

Radical constructivism, thus, is radical because it breaks with convention and develops a theory of knowledge in which knowledge does not reflect an 'objective' ontological reality.

Paul Watzlawick

Philosophy stands in need of a science which shall determine the possibility, principles, and extent of human knowledge à priori.

Immanuel Kant

Because of its concrete content, sense-certainty immediately appears as the richest kind of knowledge, indeed a knowledge of infinite wealth for which no bounds can be found, either when we reach out into space and time in which it is dispersed, or when we take a bit of this wealth, and by division enter into it. Moreover, sense-certainty appears to be the truest knowledge ... but, in the event, this very certainty proves itself to be the most abstract and poorest truth. All that it says about what it knows is just that it is; and its truth contains nothing but the sheer being of the thing.

Georg Wilhelm Friedrich Hegel

There are no a priori obstacles to the scientific knowledge of the mind, but the scientific knowledge of the mind is not all the knowledge of the mind that there is. This is not an objection to science, it is just a distinction between different kinds of knowledge.

Tim Crane

A priori one should expect a chaotic world which cannot be grasped by the mind in any way... The kind of order created by Newton's theory of gravitation...is wholly different. Even if the axioms of the theory are proposed by man, the success of such a project presupposes a high degree of ordering of the objective world.... That is the "miracle" which is being constantly reinforced as our knowledge expands.

Albert Einstein

All those formal systems, in mathematics and physics and the philosophy of science, which claim to give foundations for certain truth are surely mistaken. I am tempted to say that we do not look for truth, but for knowledge. But I dislike this form of words, for two reasons. First of all, we do look for truth, however we define it, it is what we find that is knowledge. And second, what we fail to find is not truth, but certainty; the nature of truth is exactly the knowledge that we do find.

Jacob Bronowski

Philosophy's position with regard to science, which at one time could be designated with the name "theory of knowledge," has been undermined by the movement of philosophical thought itself. Philosophy was dislodged from this position by philosophy.

Jurgen Habermas

The judgment that human life is worth living, or rather can and ought to be made worth living, ... underlies all intellectual effort; it is the a priori of social theory, and its rejection (which is perfectly logical) rejects theory itself.

Herbert Marcuse

In mysticism, knowledge cannot be separated from a certain way of life which becomes its living manifestation. To acquire mystical knowledge means to undergo a transformation; one could even say that the knowledge is the transformation. Scientific knowledge, on the other hand, can often stay abstract and theoretical. Thus most of today’s physicists do not seem to realize the philosophical, cultural and spiritual implications of their theories.

Lois McMaster Bujold

For many ages it has been allowed by sensible men, Nihil est in intellectu quod non fuit prius in sensu: That is, There is nothing in the understanding which was not first perceived by some of the senses. All the knowledge which we naturally have is originally derived from our senses. And therefore those who want any sense cannot have the least knowledge or idea of the objects of that sense; as they that never had sight have not the least knowledge or conception of light or colours.

John Wesley

Philosophy is that part of science which at present people chose to have opinions about, but which they have no knowledge about. Therefore every advance in knowledge robs philosophy of some problems which formerly it had ...and will belong to science.

Bertrand Russell

The test of a theory is its ability to cope with all the relevant phenomena, not its a priori 'reasonableness'. The latter would have proved a poor guide in the development of science, which often makes progress by its encounter with the totally unexpected and initially extremely puzzling.

John Polkinghorne

Philosophical questions are not by their nature insoluble. They are, indeed, radically different from scientific questions, because they concern the implications and other interrelations of ideas, not the order of physical events; their answers are interpretations instead of factual reports, and their function is to increase not our knowledge of nature, but our understanding of what we know.
