"I'm a social scientist. The documents should be declassified unless there is a danger in doing so. It is unlikely that after so many years there is a danger in declassifying it (documents)," Pfaff, who is on a visit to the city, told journalists here.
"I cannot understand why the documents cannot be declassified after so many years...The documents also relates to Indian and international history," she said.
Pfaff was speaking on the sidelines of the release of a book-cum-diary named 'A Salute' on her father.
Asked about the proposed memorial on Netaji at his ancestral home at Kodalia village in South 24 Parganas district, she said, "It is a nice step. It'll help the people of the area."
When pointed out that there were objections to the memorial by Forward Bloc as it would mean that Netaji is dead, she said, "I don't understand how it will endorse whether he is dead or alive after so many years. We can all presume that he is dead unless you believe in eternal life."
"It is his 116th birthday and it is unlikely he is alive now," she said, adding, "But I would like to say that we have a lot more to learn from his life and work."
