Abstract
In this paper, we shall consider the question of whether, in a context such as that of Spain that is, a context where a particular religion has been historically dominant, and within the boundaries of political liberalism, it is possible to find a reasonable argument in favour of what is termed positive laicism. In order to do so, we must first briefly clarify what this type of laicism consists of. Below we shall explore some of the arguments which could be used to defend it. We shall attempt to demonstrate that the majority of these arguments are lacking in some relevant aspect. The only defence of positive laicism that seems reasonable is one based on reasons of a politico-cultural nature which, in the context mentioned, mean that said positive laicism must be asymmetric.
