Some claim that it was because his ideas were so profound that they could not be communicated in lectures, but if truth be told it is more likely that the reason was because he was a poor communicator with handwriting which was almost impossible to read. [I will agree that such problems have not stopped others lecturing!]
Ilang claim na ito ay dahil ang kanyang mga ideya ay kaya mahimbing na sila ay hindi communicated sa lektura, ngunit kung ang katotohanan ay sinasabi na ito ay mas malamang na ang dahilan ay dahil siya ay isang mahinang tagapagbalita sa sulat-kamay na kung saan ay halos imposible na basahin. [Ako ay sumasang-ayon na tulad ng mga problema ay hindi tumigil iba lecturing!]
