Idleness among children, as among men, is the root of all evil, and leads to no other evil more certain than ill temper.

Legacy
Several local schools and the Hannah More Academy at Reisterstown Maryland are named in her honour. In her old age philanthropists from all parts made pilgrimages to see the bright and amiable old lady and Hannah More retained all her faculties until within two years of her death.

She can be said to have made three reputations in the course of her long life: as a poet and playwright in the circle of Johnson Reynolds and Garrick as a writer on moral and religious subjects and as a practical philanthropist.
