In a world where magic really does exist, and can do the things it does in D&D, why would someone ever choose not to learn how to cast spells?
Ten Reasons Why You Might Not Learn Magic
1. Your culture/religion is superstitious of magic and fears magic-users.
2. Magic is outlawed and witch-hunters track down and torture magic-users. Conversely, magic may be so desired that all magic-users are drafted by the imperial army.
3. You have a relationship or belief that holds you back from learning magic. For example, your rival sibling learned magic already and you couldn't compete to his/her expertise.
4. A council strictly regulates who may learn magic and require a deadly test. Alternately, magical mentors are extremely rare and may be dying out.
5. Magical components and education are cost prohibitive (and magical training may require a decade or more). Sorcerous magic may be more easily accessible, but only to those with the proper bloodline - which may be lots of trouble.
6. There are dangerous consequences to using magic. (Not in D&D core, but a staple of fantasy fiction, e.g. Ursula K LeGuin's
Earthsea series)
7. Spell lists are extremely limited in the campaign world (perhaps to "support magic"), or magic can fail, or magic doesn't work in all places equally. Thus magic's power is severely curtailed.
8. There are limits on multi-classing in the campaign world, representing an "innate gift" for magic, or other barriers to becoming a magic-user.
9. "With great power comes great responsibility." Being able to wield cosmic earth-bending power comes with temptations, moral dilemmas, and duties that few can fathom. For example, you might shift toward a True Neutral alignment, be required to choose between your nation and your magical order, or learn the horrifying truth that magic-users are all that stands between reality and alien spirits.
10. The character tried to learn magic but failed his/her apprenticeship, and was forced to leave his mentor in shame. Perhaps they failed a test, lacked the necessary wisdom (or intelligence), or misused their magical ability and had it stripped from them.
