This disparity is a part of human nature. From the Biblical book of Romans 7:19
" For the good that I want, I do not do, but I practice the very evil that I do not want. "
Based on this, there is either a lack of connection between words and actions, or they might be inverse indicators.
Quite a simple quote. This suggests to investigate the disparity and remove it, does it not? Maybe it is not human nature but a learned behavior. Do young children act this way?
Young children seek only personal desire. Only with age do they become aware of the needs of others. Then the battle begins. Yes. I think the quote intends for the reader to remove the difference, yet even with effort it remains.
