We show that in the Gromov space of isometry classes of pointed proper metric spaces, the equivalence relations defined by existence of coarse quasi-isometries or being at finite Gromov–Hausdorff distance cannot be reduced to the equivalence relation defined by any Polish action.

This article studies the "Theory of the Pur Object" in the Spanish philosopher Antonio Millán-Puelles, relating it to the Scholastics and to of Husserl and Hartmann.

We shall study the modes of self-consciousness such as they have been described by A. Millán-Puelles in his work.
