I believe the answer is:
carlyle
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">scottish historian</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for carlyle that I've seen before include "Thomas --, Scottish social historian" , "Scottish writer" , "Thomas ---, Victorian sage" , "Thomas -, nineteenth century British essayist/historian" , "Victorian historian" .)
