Dostoevsky is a poet. But if that quote is exemplary of his philosophy, then I wonder if he really knows what makes someone "good."

Wanting to be a good person is what makes someone a good person. It is the very beginning, the spark, the catalyst, that can drive their hopes, their thoughts, their words, their actions, their whole being towards goodness. For most people though, we cannot expect them to develop goodness through sheer force of will. It has to be developed and nurtured and brought forth, by educating people about what is important and just, by encouraging them and inspiring them through our actions and examples of goodness in the world that surrounds us, and by empowering them by not only creating an environment that promotes good behavior, but by creating opportunities for them to make choices that allow them to express their good will, their generosity, their kindness, their humility. Goodness in a person is more than just the product of personal choices, it is a reflection of the world they live in. It's incumbent upon all of us to help build that world.
