Mutis divided his lecture into two sections. In the first one, he discussed the general aspects of his Copernicanism, openly declaring to be a Copernican, and relating the Copernican system to the Newtonian methodology in which mathematics provides the basis for the counter-intuitive assertions derived from the postulation of the motion of the earth. In the second section, on the other hand, he decisively developed the arguments for supporting the Copernican system, presenting as a thesis the motion of earth. Thereby, he discussed three physical arguments that recall Galileo’s arguments in his Dialogue in which he comments the motion of bodies in earthly atmosphere and advances a theory of tides that constitutes, for Galileo, the main evidence …show more content…
In both Galileo’s and Mutis’ argumentations, it is discussed the counter-arguments derived from the Ptolemaic system of the world by considering the earth as a vessel in which everything that is contained moves along with the vessel itself. Despite that Mutis is limited to presenting in a general way the arguments –leaving them undeveloped-, the use of the cases that Galileo contemplates in the second day of his Dialogue reveals us that he had them in mind for his …show more content…
It is presented in his third argument for supporting the Copernican system as a thesis, which is an extension of the consequences and experimental implications of the precedent argument. According to him, when any basin containing any kind of fluid is put in motion, the substance that it contains moves in the opposite direction. He exemplifies this by considering some experiments with glass basins that are completely filled with water and put in
