A Quote by Antonie van Leeuwenhoek

I have often endeavoured to view the circulation of the blood in terrestrial animals, but without success, by reason that no parts of their bodies were sufficiently transparent.
I have divers times endeavoured to see and to know, what parts the Blood consists of; and at length I have observ'd, taking some Blood out of my own hand, that it consists of small round globuls driven through a Crystalline humidity or water.
How came the bodies of animals to be contrived with so much art, and for what ends were their several parts? Was the eye contrived without skill in Opticks, and the ear without knowledge of sounds?...and these things being rightly dispatch’d, does it not appear from phænomena that there is a Being incorporeal, living, intelligent...?
. . . it is difficult for Europeans to appreciate the sentiment. Other nations kill animals by wholesale and kill one another; they exist in a sea of blood. A European said that the reason why in India animals were not killed was because it was supposed that they contained the spirits of ancestors. This reason was worthy of a savage nation who are not many steps from the brute.
In the case of those solids, whether of earth, or rock, which enclose on all sides and contain crystals, selenites, marcasites, plants and their parts, bones and the shells of animals, and other bodies of this kind which are possessed of a smooth surface, these same bodies had already become hard at the time when the matter of the earth and rock containing them was still fluid. And not only did the earth and rock not produce the bodies contained in them, but they did not even exist as such when those bodies were produced in them.
We have seen that blood united to blood in the case of but remotely connected species of animals, kills; blood united to blood in the case of more closely allied species of animals does not kill. The physical organism of man survives when strange blood comes in contact with strange blood, ... but clairvoyant power perishes under the influence of this mixing of blood, or exogamy.
I do not think the division of the subject into two parts - into applied mathematics and experimental physics a good one, for natural philosophy without experiment is merely mathematical exercise, while experiment without mathematics will neither sufficiently discipline the mind or sufficiently extend our knowledge in a subject like physics.
In the old covenants the people were sprinkled with blood of calves without, in their bodies, to bind them to keep the law; else we were bound to just damnation, for the breaking of it.
If all bank loans were paid, there would not be a dollar of coin or currency in circulation. Someone has to borrow every dollar we have in circulation. We are absolutely without a permanent money system.
Oil your hair and take a head massage as often as possible for better blood circulation.
There is no exercise that can take the place of walking. by it the circulation of the blood is greatly improved. Walking, in all cases where it is possible, is the best remedy for the diseased bodies, because in this, all of the organs of the body are brought into use.
If the circulation of blood theory could not have been discovered without vivisection, the human kind could well have done without it.
Success, in my view, is the willingness to strive for something you really want. The person not reaching the top is no less a success than the one who achieved it, if they both sweated blood, sweat and tears and overcame obstacles and fears. The failure to be perfect does not mean you're not a success.
I am afraid of blood, but for some reason often I put blood in my photos... I don't know why.
Whatever may be the reason, whether it was that Hitler thought he might get away with what he had got without fighting for it, orwhether it was that after all the preparations were not sufficiently complete--however, one thing is certain: he missed the bus.
What we're seeking to do is become transparent. A transparent window on reality. But that takes time to do. We're starting with a very solid, objectified view of ourselves and existence
The choicest gift of God to man, the gift of reason; and having endeavoured to force upon himself the belief of a system against which reason revolts, he ungratefully calls it human reason; as if man could give reason to himself.
