The article explores the connection between the rule of law and the right to freedom of thought, conscience, and religion from an empirical and theoretical perspective. The author posits that the two are not merely interdependent, but that freedom of thought, conscience, and religion is foundational for embedding the rule of law because a state needs to facilitate freedom of thought, conscience, and religion to encourage the exploration of virtue to inform consensus around society’s common norms. This virtue-building role of freedom of thought, conscience, and religion gives the human right its foundational role for creating the conditions required for embedding the rule of law. This conclusion is drawn from Martin Krygier’s analysis of the sociological conditions necessary to embed the rule of law and a comparison of the worldwide rule of law, religious freedom, and happiness indexes. To support a universal approach to the human right and to underpin the identified essentiality of it, the author proposes a theoretical approach grounded in the theory of common grace; Rowan Williams’s other-regarding communal approach to rights; and the framework for plural living together proposed by Herman Dooyeweerd. The author posits that this approach could be adapted with a plural metanarrative to accommodate dialogue around virtue building and dispute resolution within societies with very different outlooks.
