Ludus enim liberalis hominis, qui scilicet intendit propria sponte bonum agere, differt a ludo hominis servilis, qui circa servilia occupatur.
Et ludus hominis disciplinati, qui scilicet instructus est qualiter debeat ludere, differt a ludo hominis indisciplinati, qui nulla disciplina in ludo refrenatur.
Ludus enim est quaedam quies et remissio animi quam superabundanter quaerit lusivus.
It is apparently opposed to the sense of "ludus" that is greatly valued in Brazilian culture.
On the other hand, Brazilian writers have time and again described and praised the value of a sense of "ludus", playfulness, therefore indicating that it is a value of their own culture.
To solve the problem, an analogy is drawn between the sense of playfulness, "ludus", described and praised by Brazilian authors, and the sense of detachment proposed by Jacques Ellul as a condition for bringing about real civilization with technological progress.
