Abstract
The Principle of Continuity is a major premise in what can be called the “Continuity-Argument for Panpsychism” : If we, as complex conscious organisms, are the evolutionary products of originally inorganic components and processes, and consciousness is a metaphysically irreducible feature, thenconsciousness must have already been a feature of these fundamental components, assuming there is continuity between the inorganic and the organic. This argument faces one serious objection, based on the possible vagueness of consciousness: If consciousness is a feature of organisms which is gradually gained at some later phylogenetic stage the conclusion of CAP is false. In my paper I defend the assumption that consciousness cannot be vague with the goal of concluding that CAP is sound
