There are no sects in geometry

Morality is everywhere the same for all men, therefore it comes from God; sects differ, therefore they are the work of men.

When we see religion split into so many thousand of sects, and I may say Christianity itself divided into its thousands also, who are disputing, anathematizing and where the laws permit burning and torturing one another for abstractions which no one of them understand, and which are indeed beyond the comprehension of the human mind, into which of the chambers of this Bedlam would a man wish to thrust himself.

[Letter to George Logan, 12 November 1816]

I am convinced that everything has come down to us from the banks of the Ganges, - astronomy, astrology, metempsychosis, etc. It is very important to note that some 2,500 years ago at the least Pythagoras went from Samos to the Ganges to learn geometry...But he would certainly not have undertaken such a strange journey had the reputation of the Brahmins' science not been long established in Europe.

History is no more than the portrayal of crimes and misfortunes

No problem can withstand the assault of sustained thinking.
