Sagacity Quotes
If you only notice human proceedings, you may observe that all who attain great power and riches, make use of either force or fraud; and what they have acquired either by deceit or violence, in order to conceal the disgraceful methods of attainment, they endeavor to sanctify with the false title of honest gains. Those who either from imprudence or want of sagacity avoid doing so, are always overwhelmed with servitude and poverty; for faithful servants are always servants, and honest men are always poor; nor do any ever escape from servitude but the bold and faithless, or from poverty, but the rapacious and fraudulent. God and nature have thrown all human fortunes into the midst of mankind; and they are thus attainable rather by rapine than by industry, by wicked actions rather than by good. Hence it is that men feed upon each other, and those who cannot defend themselves must be worried.
Niccolò Machiavelli
.. Your Lordship [Dartmouth], I am sure, will be sensible of the dress thus far, but I defy any but a painter of some sagacity (and such you see I am, my Lord) to be well aware of the different effects which one part of a picture has upon another, and how the eye may be cheated as to the appearance of size, &c., by an artful management of the accompaniments. A tune may be so confused by a false bass that if it is ever so plain, simple, and full of meaning it shall become a jumble of nonsense, and just so shall a handsome face be overset by a fictitious bundle of trumpery of the foolish painter's own inventing.... Lady Dartmouth's [second/repainted] picture will look more like and not so large when dressed properly..
Thomas Gainsborough
I... chose rather to publish... in puris Naturalibus, or as they were produced as first, than be at the Trouble of reducing them into any other Form... I could not bear the Pains of reading over again a great Part of these Things; either from my being tired with them, or not caring to undergo the Pains and Study in new modelling them. But I have done in this as weakly Mothers, who give up their Offspring to the Care of their Friends, either to Nurse and bring up, or abandon to the wide World. One of which is Mr. Isaac Newton, my Collegue, a Man of great Learning and Sagacity, who revised my Copy and noted such Things as wanted Correction, and even gave me some of his own, which you will see here and there interspersed with mine, not without their due Commendations. The other is Mr. John Collins (who may be deservedly called the Mersennas of our Nation, Born to promote this Science, both with his own Labours, and those of others. Who with much Trouble took care of the Edition.
Isaac Barrow
Alike in the highest regions of speculation and in the smaller practical concerns of daily life, her mind was the same perfect instrument, piercing to the very heart and marrow of the matter; always seizing the essential idea or principle. The same exactness and rapidity of operation, pervading as it did her sensitive as well as her mental faculties, would, with her gifts of feeling and imagination, have fitted her to be a consummate artist, as her fiery and tender soul and her vigorous eloquence would certainly have made her a great orator, and her profound knowledge of human nature and discernment and sagacity in practical life, would, in the times when such a carrière was open to women, have made her eminent among the rulers of mankind. Her intellectual gifts did but minister to a moral character at once the noblest and the best balanced which I have ever met with in life.
John Stuart Mill
