Abstract
This paper has the following structure: in the first section, I report on the historical and philosophical roots of the problems of knowledge and justification; in the second, I lay out the distinction between truth and epistemic justification; the third section is devoted to the problem of circularity, a problem often attributed to coherentism; in the fourth section, I introduce an unorthodox notion of justification, systemic justification; in the fifth, I present and criticize another unorthodox notion of justification, non-linear inferential justification; in the sixth, I discuss a few other distinctions and focus on the propositional and doxastic forms of justification; the examination of those forms is subsequently developed in the seventh section; I conclude with a reflection on the nature and limits of my proposal.
