I need your opinion/help, guys. Well-know American logician H. Curry once expressed the opinion that in spite of the fact that it seemed to be absolutely impossible to explain Russell's paradox in terms of conventional 19th century logic, it may happen in modern days that some error would be identified. I consider my paper (link below) to give the ultimate answer to this challenge, identifing the one. https://docs.google.com/file/d/0B_tihhgZ1L4wOUN3aTVFN05sXzQ/edit?usp=sharing I hope you will become interested and give your valuable opinion on the paper. Such feedback will help me a lot! The paper is rather small and written in a clear organized way – I do not think it will take more than 30 minutes from a person knowing the very basics of math to get it all. Thanks a lot in advance! Dan P.S. The paper is in English, though, of course, it is not English of an English speaking person.
