I just had cause to look up Arnold Toynbee
“To many world historians today, Arnold J. Toynbee is regarded like an embarrassing uncle at a house party. He gets a requisite introduction by virtue of his place on the family tree, but he is quickly passed over for other friends and relatives.”
Michael Lang, Globalization and Global History in Toynbee.
That said - maybe his time is come back;
“In general, historians pointed to his preference of myths, allegories, and religion over factual data.”
PS : His grandaughter is Polly Toynbee
