 In principle two strands to the debate about the role of concepts in experience contents can be distinguished: whether experiences have any contents that cannot be believed, and whether concepts play the same role in the contents of beliefs as they play in the contents of experience. Some philosophers accept the same-content thesis and belief-conceptualism but deny experience-conceptualism, e.g., Tye (2005). Speaks (2005, 2009) defends same-content thesis but denies experience-conceptualism.
