alleryआधुनिक तर्कशास्त्र में, क्या 'सभी A, B हैं' तब सत्य हो सकता है जब कोई भी A न हो?
Aकेवल तभी जब यह अंशव्यापी हो
Bकेवल तभी जब B रिक्त हो
Cनहीं, इसे असत्य होना चाहिए
Dहाँ, यह सत्य हो सकता है
Answer & Solution
Correct answer: D. हाँ, यह सत्य हो सकता है
आधुनिक तर्कशास्त्र सर्वव्यापी कथनों के लिए अस्तित्वपरक भावार्थ को अस्वीकार करता है, इसलिए किसी रिक्त वर्ग के लिए वे स्वतः/शून्यतः सत्य होते हैं।
