子曰，德之不修，学之不讲，闻义不能徒，不善不能改，是吾忧也。
Modern Chinese Guide
孔子说：品德不去修养，学问不去讲习，听到合乎义理的事却不能去做，有了缺点不能改正，这些都是我所忧虑的。
James Legge Translation
The Master said, "The leaving virtue without proper cultivation; the not thoroughly discussing what is learned; not being able to move towards righteousness of which a knowledge is gained; and not being able to change what is not good:—these are the things which occasion me solicitude."
