We argue that, by virtue of an ambiguity in the definition of the circulation of the vector potential, a modified quantization condition comes out for the electric charge that opens the way for understanding fundamental fractional charges. One does not, any longer, need to rely on the existence of a magnetic monopole to justify electric charge quantization.7 pages, 1 eps figure, title changed, references added, minor changes in the text, work presented at the Fourth International Winter Conference on Mathematical Methods in Physics, 09 - 13 August 2004, Centro Brasileiro de Pesquisas Fisicas (CBPF/MCT), Rio de Janeiro, BrazilQuantum PhysicsHigh Energy Physics - Theorytext
