Based on Heidegger and Lacan, we think the relation between science, anguish and nothing. We find a similar approach of the problem of science in Heidegger and Lacan: in both authors, the science's unfamiliarity with the anguish has to do with something we call, using a term of Lacan, the forclusion of the nothing or, using the expression of Heidegger, not to want to know of the nothing. Remaining itself in the Metaphysical tradition, science does not believe that the nothing can have effects. However, what Heidegger and Lacan show are that the nothing not only can have effects, but also be cause of many things, as, for example, the anguish.
