This is perhaps the only sentence in it that I cannot comprehend.It is contrary to Nature to know what the future holds, for otherwise, the knowledge would not be effaced in the 'river of oblivion'.
Despite having discussed it with Tom on the forum, I still cannot understand how they can do future prediction (they said they can do it up to 100 years in advance) and yet they say it is bad to know what the future holds. 'To know' what the future holds certainly means 'to predict', since it is impossible for anyone to truly know what the future holds until it has come to pass. What do you think?
