For Kant, the predisposition to good (like Calvin's 'seed of goodness') is in one way more fundamental to us than the overlying propensity to evil, and in one way it is less fundamental. The predisposition to good is more fundamental because it is essential to us; we cannot lose it without ceasing to be human. The propensity to evil is in that way less fundamental, because we can lose it, and indeed we should lose it, without ceasing to be human. On the other hand, the propensity to evil is in a different way more fundamental. It is our root maxim when we are born.
