Mi konsideras la disciplinon tre grava pedagogia faktoro. Mi estas nek for fera disciplino, nek por troa liberemo. Mi pledas por racia kaj memdirekta disciplino… La vera scienculo… bezonas memvolan feran disciplinon, por koncentri ĉiujn siajn kapablon al tasko… La blindan disciplinon mi tute rifuzas, ĉar ĝi ne venas de-interne. Mi atingas disciplinon per interesigo, ŝatigo de la objekto, kaj ne per trudo… La discipliniteco estas kompreneble ne nur ekstera kadro, sed ankaŭ interna psika kapablo. La eduko al disciplino ĝenerale disvolvas kapablojn, ĉar ĝi samtempe trejnas ankaŭ al persisto, volforto kaj atentemo.
“I consider discipline to be a very important pedagogic factor. I am neither for iron discipline, nor for excessive freeness. I plead for rational and self-directed discipline… The true scientist… needs voluntary iron discipline, in order to focus all their capability on task… I completely refuse blind discipline, because it does not come from inside. I achieve discipline through making one interested, making one like the object, and not by imposing… The disciplineness is of course not only external frame, but also internal psychological capability. The upbringing towards discipline in general develops capabilities, because at the same time it also trains persistence, willpower, and attentiveness.”
This is a little ambiguous; does he mean self-control or punishment?
Definitely the former. For more context:
