Sin is not only manifested in certain acts that are forbidden by divine command. Sin also appears in attitudes and dispositions and feelings. Lust and hate are sins as well as adultery and murder. And, in the traditional Christian view, despair and chronic boredom - unaccompanied by any vicious act - are serious sins. They are expressions of man's separation from God, as the ultimate good, meaning, and end of human existence.
Mortimer AdlerImaginative literature primarily pleases rather than teaches. It is much easier to be pleased than taught, but much harder to know why one is pleased. Beauty is harder to analyze than truth.
Mortimer AdlerHabits are formed by the repetition of particular acts. They are strengthened by an increase in the number of repeated acts. Habits are also weakened or broken, and contrary habits are formed by the repetition of contrary acts.
Mortimer AdlerIf you are reading in order to become a better reader, you cannot read just any book or article. You will not improve as a reader if all you read are books that are well within your capacity. You must tackle books that are beyond you, or, as we have said, books that are over your head. Only books of that sort will make you stretch your mind. And unless you stretch, you will not learn.
