Instilling a general rule, or maxim, and then willing it to happen is a sign that moral permissibility is present. The right actions are those that follow these guidelines. Making it a rule that every item of information be communicated between the owners for the duration of the home's existence would ensure moral permissibility. This concept is known as universalizability. For the seller, acting under the assumption that no one would buy the house because of the snakes could cause him or her not to reveal the truth. However, the seller would be honest about the condition of the home in all other respects. This would be an exception to the universal maxims favored by Kant. Exceptions are seen as moral weaknesses and, therefore, have no substantiality within Kant's ethical theory. The exclusion of snakes during the sales process is the weak point. An outcome cannot be consistently determined, but morally right decision making through maxims and will can help provide the best outcome. Universal maxims serve more than one purpose and benefit everyone
