Ignorant ingrates we may often be

“We stand upon the foundations reared by the generations that have gone before, and we can but dimly realise the painful and prolonged efforts which it has cost humanity to struggle up to the point, no very exalted one after all, which we have reached. Our gratitude is due to the nameless and forgotten toilers, whose patient thought and active exertions have largely made us what we are.” – Sir James George Frazer, The Golden Bough
