Care of the soul by Jan Patočka and its necessity in the constitution of humanity
KOUBA, Vojtěch
The work deals with the idea of caring of the soul, as presented by Jan Patočka and its necessity for the constitution of humanity, which seeks to do good on the personal, societal, and global, ecological level. The first part deals with the care of the soul by Socrates and in the Platonian polis, there are highlighted some concepts related to education of its guardians. Then there are described three existential movements, which Jan Patočka educes from the care of the soul and its three aspects. In another part is firstly implied relation between the care of the soul and philosophy, and then the original theme and herewith the aim of these two activities. The last part is an attempt to show how it can happen, that we are talking about ?succour from philosophy?, then how to use the care of the soul for we could see the world as our home and what the consequences will be there, when we don't care of the soul and instead we paying attention only to the exact knowledge of modern science.
