From The History of England from the Ascension of James II by Thomas Babington Macaulay, Vol. 1, Chapter 1 (Kindle Edition):
"Everywhere there is a class of men who cling with fondness to whatever is ancient, and who, even when convinced by overpowering reasons that innovation would be beneficial, consent to it with many misgivings and forebodings. We find also everywhere another class of men, sanguine in hope, bold in speculation, always pressing forward, quick to discern the imperfections of whatever exists, disposed to think lightly of the risks and inconveniences which attend improvements and disposed to give every change credit for being an improvement. In the sentiments of both classes there is something to approve. But of both the best specimens will be found not far from the common frontier. The extreme section of one class consists of bigoted dotards: the extreme section of the other consists of shallow and reckless empirics."
