Sir Karl Raimund Popper (28 July 1902 – 17 September 1994) was an Austrian–British philosopher, academic and social commentator. One of the 20th century's most influential philosophers of science, Popper is known for his rejection of the classical inductivist views on the scientific method in favour of empirical falsification made possible by his falsifiability criterion, and for founding the Depa Although Popper was an advocate of toleration, he also warned against unlimited tolerance. In The Open Society and Its Enemies, he argued: Unlimited tolerance must lead to the disappearance of tolerance. If we extend unlimited tolerance even to those who are intolerant, if we are not prepared to defend a tolerant society against the onslaught of the intolerant, then the tolerant will be destroyed, and tolerance with them. In this formulation, I do not imply, for instance, that we should always suppress the utterance of intolerant philosophies; as long as we can counter them by rational argument and keep them in check by public opinion, suppression would certainly be most unwise. But we should claim the right to suppress them if necessary even by force; for it may easily turn out that they are not prepared to meet us on the level of rational argument, but begin by denouncing all argument; they may forbid their followers to listen to rational argument, because it is deceptive, and teach them to answer arguments by the use of their fists or pistols. We should therefore claim, in the name of tolerance, the right not to tolerate the intolerant. We should claim that any movement preaching intolerance places itself outside the law, and we should consider incitement to intolerance and persecution as criminal, in the same way as we should consider incitement to murder, or to kidnapping, or to the revival of the slave trade, as criminal.

Considered victorious in the Contemporary Age, democracy becomes part of Politics and Law, a figure considered fundamental and which best promotes the dignity of the person. As societies are dynamic within and among themselves, manifestations that diverge from democratic regime arise and are the subject of study and debate. Karl Popper introduces the divergence to democracy from the paradox of tolerance, which deals with how those intolerants of democracy should be treated by it. How to deal with these intolerants? This essay aims to problematize a border situation between Politics and Law through democratic success and how its premise of tolerance deals with the paradox coined by Karl Popper. There is more: the definition of democracy depends on the figure of tolerance, but both are constantly treated from a judicial perspective, especially by minorities. This text combats the subversion of the majority principle through the so-called tyranny of the minority, as democratic pillars must be developed under the aegis of the majority, clearly with respect for the juridical interests of all subjects.

For Rainer Forst, the limits must be established at the onset of intolerance; because tolerance implies reciprocity, it can only be demanded for those who are tolerant ... paradox,” to which Forst responds, arguing that a ...
