Il problema del tempo e dello spazio in Jakob von Uexküll

The Question of Time and Space in Jakob von Uexküll – The concepts of time and space that, in the first half of twentieth century, emerge from the reflections of Estonian biologist Jakob von Uexküll (1864-1944) distinguishes itself thanks to a particular transformation of Kant’s notion of space as “pure intuition”, which aims to set the transcendental aspect of intuition within a dimension that does not reject the physical-mathematical determinations, but recon-figures them so to make them suitable to express the sense that is assigned to time and space in the life of every living being. In this perspective, the metric-quantita¬tive space of extension appears as a special case of a much more fundamental topological space founded on internal and external relations that the signs take on objects in different biological subjects, understood not as simple empirical subjects, but as places of establishment of the meanings of experience.
