Presumption

Presumption, as we use the word here, means the immoderateand unreasonable assuming that one can do what actually lies beyondone’s power to perform. Since presumption conflicts withreason, it is sinful.

Presumption is an evil opposed to magnanimity. Formagnanimity is greatness of mind and purpose for honorableachievement which, however difficult, lies within a person’spower to attain. But presumption reaches with ill-foundedconfidence for what lies beyond its power to grasp.
