Whereas Plato's main problem had been the organization of the perfect state, and Aristotle's intellect had ranged with fresh interest over all departments of the knowable, political speculation had become a mockery with the extinction of free political life, and knowledge as such had lost its freshness for the Greeks of the Roman Empire.
It appears, therefore, that Spencer ultimately describes the Knowable in terms of the mechanical conceptions of matter and motion, and that this must give a materialistic colouring to his philosophy.
Still more unequivocal was the sceptical nihilism expressed by Gorgias: - (I) nothing exists; (2) if anything existed, it would be unknowable; (3) if anything existed and were knowable, the knowledge of it could not be communicated.
It may be urged in reply that the synthetic philosophy could be made consistent by transferring the knowable resistance and persistence of the unknowable noumenon to knowable phenomena on the one hand, and on the other hand by maintaining that all phenomena from the original nebula to the rise of consciousness are only ` 0 impressions produced on consciousness through any of the senses," after all.
If everything knowable is an example of evolution, and evolution is by definition a transformation of matter and motion, then everything knowable is an example of a transformation of matter and motion.
But, in spite of these materialistic tendencies, he followed Hume in reducing matter and everything knowable to phenomena of consciousness; and, supposing that nothing is knowable beyond phenomena, concluded that we can neither affirm nor deny that anything exists beyond, but ought to take up an attitude which the ancient sceptics called Aphasia, but he dubbed by the new name of Agnosticism.
- Noumenal Idealism In Germany Noumenal idealism is the metaphysics of those who suppose that all known things are indeed mental, but not all are phenomenal in the Kantian sense, because a noumenon is knowable so long as by a noumenon we mean some mental being or other which we somehow can discover beyond phenomena.
Starting from Fichte's " Wissenschaftslehre," Schelling accepted the whole process of mental construction, and the deduction that noumena are knowable products of universal reason, the Absolute Ego.
He got the hint of a noumenal will from Kant; but in regarding the noumenal as knowable, because mental, as well as in the emphasis he laid on the activity of will, he resembled Fichte.
On the contrary, his contention is that of Fechner - that all knowable things are inner psychical realities beneath outer physical appearances - the invisible symbolized by the visible.
Riehl, who in Der philosophische Kriti .cis- mus (1876, &c.) proposes the non-Kantian hypothesis that, though things in themselves are unknowable through reason alone, they are knowable by empirical intuition, and therefore also by empirical thought starting from intuition.
The most comprehensive view of Rosmini's philosophical standpoint is to be found in his Sistema filosofico, in which he set forth the conception of a complete encyclopaedia of the human knowable, synthetically conjoined, according to the order of ideas, in a perfectly harmonious whole.
Locke next inquired to what extent knowledge - in the way either of intuitive certainty, demonstrative certainty, or sense perception - is possible, in regard to each of the four (already mentioned) sorts of knowable relation.
The second sort of knowable relation is sometimes intuitively and sometimes demonstrably discernible.
Turning from abstract mathematical and moral relations to concrete relations of coexistence and succession among phenomena - the third sort of knowable relation - Locke finds the light of pure reason disappear; although these relations form " the greatest and most important part of what we desire to know."
The cardinal assumption of Plato's metaphysic is, that the real is definitely thinkable and knowable in proportion as it is real; so that the further the mind advances in abstraction from sensible particulars and apprehension of real being, the more definite and clear its thought becomes.
These are all knowable things, and yet there is not universal agreement on them.
The apologist must maintain (I) that Jesus of Nazareth is a real historical figure - a point well-nigh overlooked by Strauss, and denied by some modern advocates of a mythical theory; (2) that Jesus is knowable (not one " of whom we really know very little " - B.
In opposition to Aquinas, who maintained that reason and revelation were two independent sources of knowledge, Duns Scotus held that there was no true knowledge of anything knowable apart from theology as based upon revelation.
