The more necessary a thing is for living beings, the more easily it is found and the cheaper it is; the less necessary it is, the rarer and dearer it is.
Nature is nowhere accustomed more openly to display her secret mysteries than in cases where she shows tracings of her workings apart from the beaten paths; nor is there any better way to advance the proper practice of medicine than to give our minds to the discovery of the usual law of nature, by careful investigation of cases of rarer forms of disease.william harvey
Not that the earth doth yieldIn hill or dale, in forest or in field,A rarer plant.guillaume de salluste du bartas
Nothing which consists of corporeal matter is absolutely light, but that is comparatively lighter which is rarer, either by its own nature, or by accidental heat. And it is not to be thought that light bodies are escaping to the surface of the universe while they are carried upwards, or that they are not attracted by the earth. They are attracted, but in a less degree, and so are driven outwards by the heavy bodies; which being done, they stop, and are kept by the earth in their own place.johannes kepler
There are ever two ways of striving to fill one's place in the world: one is by seeking to prove one's self useful; the other, by striving to render one's self useless. The first way is the commoner and the more attractive; the second is the rarer and more noble.henry clay trumbull
The truth that Dostoevsky puts in the mouth of the Grand Inquisitor is that humankind has never sought freedom, and never will. The secular religions of modern times tell us that humans yearn to be free; and it is true that they find restraint of any kind irksome. Yet it is rare that individuals value their freedom more than the comfort that comes with servility, and rarer still for whole peoples to do so.john n. gray
There is something that is much more scarce, something finer far, something rarer than ability. It is the ability to recognize ability. The sternest comment that can be made against employers as a class lies in the fact that men of Ability usually succeed in showing their worth in spite of their employer, and not with his assistance and encouragement.elbert hubbard
