Although the Convention on the Rights of Persons with Disabilities (CRPD) proclaims the right to inclusive education, and much attention is being given to the goal of inclusive education in debates on human rights, there are doubts as to whether this right has led to a new direction in policy-making. The under-researched question is: why is there so much opposition to the implementation of the right to inclusive education? This paper examines the question by distinguishing between both the concept and practice of inclusive education. Using a specific interdisciplinary approach in order to critically analyse a legal norm, the paper looks into the very meaning of inclusive education by utilising some central conclusions from disability studies to appraise the ideal of inclusive education, and seeks to resolve related challenges by drawing upon political philosophy to investigate pragmatic solutions to the obstacles to inclusive education. This paper claims that it is thereby possible to incorporate the element of actual achievability into such an ideal.
