My opinion joined that of my predecessor. This dictionary is not to be considered as a book "all age". The explanations are very rich and detailed, but this wealth is seen with a certain heaviness because of the language used very sophisticated level, which has everything to confuse the neophyte.
It is advisable for philosophy students and confirmed in the field, but for others, this dictionary is very difficult to access, and will require understanding of efforts or decryption for the explanation of most notions which can be at the long, very tiring.
