The Bad Teacher
The scholar who knowingly speaks, writes, or teaches falsehood, who knowingly supports lies and deceptions, not only violates organic principles. He also, no matter how things may seem at the given moment, does his people a grave disservice. He corrupts its air and soil, its food and drink; he poisons its thinking and its laws, and he gives aid and comfort to all the hostile, evil forces that threaten the nation with annihilation.
Hermann Hesse, in 'The Glass Bead Game'
