"The notes of this paradoxalist do not end here, however.

He could not refrain from going on with them,

but it seems to us that we may stop here."

Notes from Underground, 1864

"In principle, it requires no particular knowledge of mathematics on the reader's part,

but only a certain familiarity with mathematical reasoning

and a certain capacity for abstract thought."
