Of course, even the general designation 'religious' includes various basic ideas or convictions, for example, the indestructibility of the soul, the eternity of its existence, the existence of a higher being, etc. But all these ideas, regardless of how convincing they may be for the individual, are submitted to the critical examination of this individual and hence to a fluctuating affirmation or negation until emotional divination or knowledge assumes the binding force of apodictic faith.
