 Many of the systematic arguments for toleration—be they religious, pragmatic, moral or epistemological—can be used as a justification for more than one of the conceptions of toleration mentioned above (section 2). The classic argument for freedom of conscience, for example, has been used to justify arrangements according to the “permission conception” as well as the “respect conception.” Generally speaking, relations of toleration are hierarchically ordered according to the first conception, quite unstable according to the conception of “coexistence,” while the “esteem conception” is the most demanding in terms of the kind of mutual appreciation between the tolerating parties. In each case, the limits of toleration seem either arbitrary or too narrow, as in the esteem conception, which only allows toleration of those beliefs and practices that can be ethically valued.
