Author Nurul Muhammad Haque argues that despite vast research – the impact on knowledge and belief in human lives are still mysterious. Sometimes what we know, either we can’t infer it or justify it, but we feel it. We’ve felt it our entire life. We start questioning our knowledge, belief, worldly judgments and human intuitions. It’s like a splinter, driving us to know more and to justify our conviction. It constructs the structure to defend what we know, believe and ultimately accepts to wake up. Ironically it’s not far from the truth. This study is part of an attempt to highlight the analysis of knowledge and belief, and the approaches to rational knowledge.
