Whenever it comes to the impossibility of vicious circle, the examples such as two bricks relied on one another are put forward; examples that seem circular, and at the same time, not only possible, but occured. These examples are generally called 'mutual circle'. If such examples are instances of vicious circle and at the same time realizable, is vicious circle not possible? If so, many discussions in philosophy and theology which are based on the impossibility of vicious circle, would all be nullified. The authors have investigated three definitions for vicious circle (need, dependency, and causality) and distinguished them from one another. They conclude that the first two definitions (need and dependency) are flawed, and 'causality' is the correct definition for vicious circle as an impossible phenomenon.
