« The techniques of history, science and fiction […] differ from each other in their suitability for dealing with data of different quantities. The ascertainment and record of particular facts is all that is possible in a field of study where the data happen to be few. The elucidation and formulation of laws is both possible and necessary where the data are too numerous to tabulate but not too numerous to survey. […] Fiction is the only technique that can be employed or is worth employing where the data are innumerable. » ~ “A study of history”, A.J. Toynbee, 1946.
