 But what about (iv)? On one way of interpreting this, it reflects the Common Kind Claim applied to veridical experiences and illusions. Furthermore, various authors hold that (iv) is supported by the continuity between veridical experiences and illusory experience (Price (1932: 32), Ayer (1940: 8–9), Broad (1952: 9), Robinson (1994: 57), Smith (2002: 26–28): the fact that they may form a “continuous series” in which they “shade into one another” (Ayer (1940: 8–9)). This, it is held, supports the idea that experiential differences between illusions and veridical perceptions are differences of “degree and not of kind” (Ayer (1940: 8)).
