A statesman or patriot, who serves our own country in our own time, has always a more passionate regard paid to him, than one whose beneficial influence operated on distant ages or remote nations; where the good, resulting from his generous humanity, being less connected with us, seems more obscure, and affects us with a less lively sympathy.
 David Hume, An Enquiry Concerning the Principles of Morals (1751). copy citation

A statesman or patriot, who serves our own country in our own time, has always a more passionate regard paid to him, than one whose beneficial influence operated on distant ages or remote nations; where the good, resulting from his generous humanity, being less connected with us, seems more obscure, and affects us with a less lively sympathy. We may own the merit to be equally great, though our sentiments are not raised to an equal height, in both cases. The judgement here corrects the inequalities of our internal emotions and perceptions;” source
