Is There a Process of Justification of Knowledge?

Knowledge has been traditionally seen as justified, true belief. However, Popper argued that the lack of a process of justifying knowledge implies that theories are always conjectures and the process of thinking about theories is critical, not justificatory. According to Popper, theories are allowed into science as conjectures and are then critiqued; if they withstand criticism, they remain, if not, they are discarded. Popper's solution to the problem of induction is that justification is not necessary initially. This perspective provides a coherent structure for science and beyond, where theories do not require specific credentials to enter science but must stand the test of criticism to remain. Popper's book 'Objective Knowledge' is suggested as a good resource to delve deeper into his solution to the problem of induction.
