In practical discourse, we can find out legal wording that is associated with ideological freedom and applied interchangeably: freedom of thought, freedom of conscience and religious freedom. In this essay, our aim consists in determining which the proper use of each expression is. For this purpose, we have observed: how the concept of ideological freedom is established in some legal systems; how it can be differentiated from religious freedom clearly but not from freedom of conscience on account of a vague material scope of validity; and why these difficulties move from conceptual to legal areas. In order to propose a convenient use to the latter expressions, we draw on BERLIN’s two concepts of liberty.

思想自由与相关法律措词

在实践中，我们可以找到与意识形态自由相关并可以互换使用的法律用语：思想自由，良心自由和宗教自由。在本文中，我们的目的在于确定每个表达式的正确用法。为此目的，我们观察到：在某些法律体系中如何建立意识形态自由的概念；由于有效范围的模糊性，如何将其与宗教自由明确区分开来，而不与良心自由区分开来；以及这些困难为何从概念领域转移到法律领域。为了方便使用后一种表达方式，我们借鉴了BERLIN的两个自由概念。
