SS t ¹ (17) From the definition of q2 and from (12), it is easy to obtain V0 qQ S (18) Now we can find the current entering the cable due to the impressed force. (18), and the third by the definition of q2. Heaviside is thus led to conclude that (Heaviside), since Q is constant for any finite value of time, the result is zero. That is, there is no current entering the cable under the action of the continuouslypresent impressed force at any finite value of the time (pp. 54-55). Even more important is his remark (Heaviside, 1899): 26 GIULIO GIORELLO and CORRADO SINIGAGLIA Is it nonsense?

Certainly after 1964 number of purposes concerning this problem have been brought forward, but in substance the Bell’s alternative remains: either Quantum Physics with just local causation but also no independent world, or Quantum Physics with causation necessarily “superluminal”8. We are here in presence of a controversy concerning concepts so important as causa, effect, temporality, movement and locality which form the nucleus of the traditional ontological problematic. As N. Cartwright suggests, contemporary physics tends intrinsically to reestablish the link with the problems of philosophical tradition: the physicist, and especially the quantum physicist, without leaving his specific discipline, is sometimes confronted with questions which involves important discussions on ontology and epistemology.

We find here the function H(t), defined as H(t) = 1, for t t 0; H(t) = 0, for t  0. ¾ E  Er ¨ ¸ ®1  2 Rt ¸¹ © RSt ¹ ° 2 Rt © °¿ ¯ (13) As Heaviside comments (Heaviside, 1899) when t is big enough, the only significant term is e, the final value. When t is smaller, the next becomes significant. When smaller still another term requires to be counted, and so on. But we must never pass beyond the smallest term in the series. As t decreases, the smallest term moves to the left. As it comes near the beginning of the series, the accuracy of calculation becomes somewhat impaired.
