Who can tell whether the parallelogram, which in our ignorance we have defined and drawn, and the whole of whose properties we profess to know, may not be all the while panting for exterior angles, sympathetic with the interior, or sullenly repining at the fact that it cannot be inscribed in a circle?
In universities and intellectual circles, academics can guarantee themselves popularity - or, which is just as satisfying, unpopularity - by being opinionated rather than by being learned.
We need be careful how we deal with those about us, when every death carries to some small circle of survivors, thoughts of so much omitted, and so little done- of so many things forgotten, and so many more which might have been repaired! There is no remorse so deep as that which is unavailing; if we would be spared its tortures, let us remember this, in time.

What an investor needs is the ability to correctly evaluate selected businesses. Note that word “selected”: You don't have to be an expert on every company, or even many.

Medicine is a science which hath been (as we have said) more professed than laboured, and yet more laboured than advanced: the labour having been, in my judgment, rather in circle than in progression. For I find much iteration, but small addition. It considereth causes of diseases, with the occasions or impulsions; the diseases themselves, with the accidents; and the cures, with the preservation.
You ought to love all mankind; nay, every individual of mankind. You ought not to love the individuals of your domestic circles less, but to love those who exist beyond it more.
Then shoulder to shoulder! Let us engirdle the little circle of the earth with the chains that bind us to each other. To one end let us aim our thoughts, and to one end let us aim our souls. Hail, dawn of liberty, behind thee is the redeeming sun.
If you have form'd a circle to go into,
Go into it yourself, and see how you would do.
They said this mystery never shall cease:
The priest promotes war, and the soldier peace.
