Quote by Edward Gibbon
But the power of instruction is seldom of much efficacy, except in those happy dispositions where it is almost superfluous.
Summary
This quote suggests that the power of teaching and guidance is often not very effective, except in individuals who already possess a naturally receptive or predisposed mindset. In other words, those who are already disposed to learning and growth may not require much instruction to thrive, while others may struggle to benefit from it. It highlights the importance of not only providing instruction, but also considering and nurturing the unique qualities and receptivity of each individual in order to maximize the potential impact of education.
