11145 | Having a belief involves the possibility of being mistaken [Davidson] |
14050 | We aim to dissolve our fears, by understanding their causes [Epicurus] |
6397 | The concept of belief can only derive from relationship to a speech community [Davidson] |
14037 | Atoms only have shape, weight and size, and the properties which accompany shape [Epicurus] |
6010 | Illusions are not false perceptions, as we accurately perceive the pattern of atoms [Epicurus, by Modrak] |
17550 | We give a mathematical account of a system of natural connections in order to clarify them [Heisenberg] |
14041 | The soul is fine parts distributed through the body, resembling hot breath [Epicurus] |

6392 | Thought depends on speech [Davidson] |
6393 | A creature doesn't think unless it interprets another's speech [Davidson] |
11144 | Concepts are only possible in a language community [Davidson] |
6395 | An understood sentence can be used for almost anything; it isn't language if it has only one use [Davidson] |
6394 | The pattern of sentences held true gives sentences their meaning [Davidson] |
14032 | Totality has no edge; an edge implies a contrast beyond the edge, and there can't be one [Epicurus] |
14033 | Bodies are unlimited as well as void, since the two necessarily go together [Epicurus] |
14034 | There exists an infinity of each shape of atom, but the number of shapes is beyond our knowledge [Epicurus] |
14035 | Atoms just have shape, size and weight; colour results from their arrangement [Epicurus] |
14038 | There cannot be unlimited division, because it would reduce things to non-existence [Epicurus] |
17549 | Seven theories in science: mechanics, heat, electricity, quantum, particles, relativity, life [Heisenberg, by PG] |
14049 | We aim to know the natures which are observed in natural phenomena [Epicurus] |
17540 | Energy is that which moves, and is the substance from which everything is made [Heisenberg] |
17541 | Energy is an unchanging substance, having many forms, and causing all change [Heisenberg] |
17548 | Maxwell introduced real fields, which transferred forces from point to point [Heisenberg] |
17533 | Radiation interference needs waves, but radiation photoelectric effects needs particles [Heisenberg] |
17532 | An atom's stability after collisions needs explaining (which Newton's mechanics can't do) [Heisenberg] |
17537 | Position is complementary to velocity or momentum, so the whole system is indeterminate [Heisenberg] |
17551 | It was formerly assumed that electromagnetic waves could not be a reality in themselves [Heisenberg] |
14043 | The void cannot interact, but just gives the possibility of motion [Epicurus] |
17543 | So-called 'empty' space is the carrier of geometry and kinematics [Heisenberg] |
14031 | Space must exist, since movement is obvious, and there must be somewhere to move in [Epicurus] |
