The following chapter addresses the complexity of contemporary philosophy with regard to the question of truth. Twentieth-century philosophy is characterized by a particular form of heterogeneity, which is especially reflected in its turn toward subjectivity—a development that began with thinkers such as Descartes, Hume, and Kant, and led to a crisis in the philosophical unity of shared inquiry. Various philosophical approaches and theories often stand in contradiction to one another. Despite this fragmentation, the discussion of truth and its justification paradoxically remains a central theme, even though it is frequently relativized or deconstructed in postmodern philosophy.
