“इतिहासात काही जागा कायमच्या रीक्त असतात. तिथं असे काही बिंदू उपलब्ध असतात, ज्यांच्या पुढं आणि मागं बऱ्याच घटना लिखित स्वरूपात उपलब्ध असतात. पण नेमकं मोक्याच्या ठिकाणी शून्य असतं. तिथं इतिहास मौन पाळतो. त्या गाळलेल्या जागी असंच घडलं असावं, असं छातीठोकपणे सांगता येत नाही. अशा रीक्त जागा इतिहासकारांना कुणावरही अन्याय न करता साकल्यानं भरून काढता येतात. जसं की, तुम्ही एखाद्या मध्ययुगीन किल्ल्यावर गेलात, तर मध्येच अशा काही अंधारवाटा लागतात. तशा अंधारवाटा आपण गतायुष्यातील अनुभव आणि सहज तर्क लावून पार करतो. इतिहासाच्या क्षेत्रात सुद्धा विवेकाची किनार धरून अशा अंधारवाटा पार करता येतात. ते फार कठीण काम नाही. एखाद्या विशिष्ट प्रसंगी इतिहास बोलत नसेल तर त्याला वेगळ्या पद्धतीनं बोलतं करता येतं.”
