＂The swamping problem＂ has been one of the most prominent issues in the contemporary epistemology in the nearly two decades. It was first proposed by L. Zagzebski who intended to attack reliabilism. She claims that once we hold a true belief, the value of the reliable belief-forming processes will be swamped by the very true belief itself. If it is right, as a reliabilist claims, knowledge is completely equivalent to true belief. This wouldn＇t be accepted by reliabilism. As the known reliabilist A. Goldman and E. Olsson present, there are two strategies, i.e. the conditional probability solution and value autonomization, which could be used to solve the swamping problem. They, however, both seem unpromising. By means of the proposal ＂against property parasitism＂ by Goldman and Olsson, there is a tenable way to clear up ＂the swamping problem＂.
