It highlights ways in which their philosophical insights have been wrongly overlooked by later writers. It explores R.L. Nettleship's posthumous publications in this field and notes that they exerted significant influences on British idealists and closely related figures, such as Bernard Bosanquet and R.G. Collingwood. The writing of other figures are also explored, not least F.H. Bradley and J.A. Smith. The article concludes by introducing in turn the remaining articles that are found in this special issue.
