Franklin is now most commonly viewed as a utilitarian moralist, a successful tradesman and printer, a shrewd propagandist and financier, the diplomat of the Revolution, and if at all as a scientist, then only as a virtuoso, fashioning devices, such as open stoves, bifocal spectacles, and lightning rods, for practical uses. Probably few general readers are aware that Franklin was a disinterested scientist in the sense that he interrogated nature with an eye to discovering its immutable laws. It is conversely supposed that Franklin himself was unaware of any inclination to pursue natural science to the exclusion of those political achievements which have identified him as one of the wiliest and sagest diplomats of the Enlightenment. It may be learned, however (not without astonishment), that Franklin almost from the beginning of his participation in politics resented the time given over to such activities, as so much time lost to his speculations and research in natural science. As early as 1752 he wistfully (though realistically) confessed that "business sometimes obliges one to postpone philosophical amusements."[i-368] A month after this, he wrote to Cadwallader Colden: "I congratulate you on the prospect you have, of passing the remainder of life in philosophical retirement."[i-369] In the midst of investigating waterspouts, he observed to John Perkins: "How much soever my Inclinations lead me to philosophical Inquiries, I am so engag'd in Business, public and private, that those more pleasing pursuits [of natural science] are frequently interrupted...."[i-370] He urged Dr. John Fothergill to give himself "repose, delight in viewing the Operations of nature in the vegetable creation."[i-371] In 1765, upon completing his negotiations in behalf of the Pennsylvania Assembly, he promised Lord Kames that he would "engage in no other" political affairs.[i-372] To the notable professor of physics of the University of Turin, Giambatista Beccaria, he wrote in 1768 from London (where he had sought to have the Stamp Act rescinded) that he had to "take away entirely" his "attention from philosophical matters, though I have constantly cherished the hope of returning home where I could find leisure to resume the studies that I have shamefully put off from time to time."[i-373] Again, in 1779, he confessed to Beccaria: "I find myself here [Passy] immers'd in Affairs, which absorb my Attention, and prevent my pursuing those Studies in which I always found the highest Satisfaction; and I am now grown so old, as hardly to hope for a Return of that Leisure and Tranquillity so necessary for Philosophical Disquisitions."[i-374] He longed (in 1782) to have Congress release him so that he might "spend the Evening of Life more agreeably in philosophic [devoted to natural science] Leisure."[i-375] He who, John Winthrop claimed, "was good at starting Game for Philosophers,"[i-376] acknowledged that he had thrown himself
