"Paschatya Darshaner Moulick Bisay Samuha" by Raspati Mondal presents a systematic exploration of the fundamental concepts that define Western philosophical inquiry. This academic work examines core philosophical problems including the nature of reality, knowledge, truth, and moral values that have engaged Western thinkers across centuries. The text analyzes how different philosophical schools have approached these enduring questions, from ancient Greek metaphysics to contemporary analytic philosophy. Important chapters such as Tattwa O Gyantattwa (তত্ত্ব ও জ্ঞানতত্ত্ব), Nitibidya O Rajnitir Darshan (নীতিবিদ্যা ও রাজনীতির দর্শন), and Bhasha O Tarkik Bishleshan (ভাষা ও তার্কিক বিশ্লেষণ) provide detailed examination of philosophical methodology and conceptual analysis. Students exploring classical Western philosophy will find this work particularly beneficial for understanding the conceptual foundations that continue to inform contemporary philosophical debates and intellectual discourse.
