A Quote by Samuel Johnson
Criticism, though dignified from the earliest ages by the labours of men eminent for knowledge and sagacity, has not yet attained the certainty and stability of science.

Science asks no questions about the ontological pedigree or a priori character of a theory, but is content to judge it by its performance; and it is thus that a knowledge of nature, having all the certainty which the senses are competent to inspire, has been attained--a knowledge which maintains a strict neutrality toward all philosophical systems and concerns itself not with the genesis or a priori grounds of ideas.
Science is not the affirmation of a set of beliefs but a process of inquiry aimed at building a testable body of knowledge constantly open to rejection or confirmation. In science, knowledge is fluid and certainty fleeting. That is at the heart of its limitations. It is also its greatest strength.
In the earliest ages science was poetry, as in the later poetry has become science.
I have indeed - praise be to God - attained my desire in this world, which was to travel through the earth, and i have attained in this respect what no other person has attained to my knowledge.
In all ages, through all the varied experience of individuals and nations, knowledge has been the power which has civilized, elevated and dignified humanity. In those countries where progress has been most rapid, the thirst for knowledge has been most intense.
I am far from any intention to limit curiosity, or confine the labours of learning to arts of immediate and necessary use. It is only from the various essays of experimental industry, and the vague excursions of mind set upon discovery, that any advancement of knowledge can be expected; and though many must be disappointed in their labours, yet they are not to be charged with having spent their time in vain; their example contributed to inspire emulation, and their miscarriage taught others the way to success.
We profess to teach the principles and practice of medicine, or, in other words, the science and art of medicine. Science is knowledge reduced to principles; art is knowledge reduced to practice. The knowing and doing, however, are distinct. ... Your knowledge, therefore, is useless unless you cultivate the art of healing. Unfortunately, the scientific man very often has the least amount of art, and he is totally unsuccessful in practice; and, on the other hand, there may be much art based on an infinitesimal amount of knowledge, and yet it is sufficient to make its cultivator eminent.
A great man, who was convinced that the truths of political and moral science are capable of the same certainty as those that form the system of physical science, even in those branches like astronomy that seem to approximate mathematical certainty. He cherished this belief, for it led to the consoling hope that humanity would inevitably make progress toward a state of happiness and improved character even as it has already done in its knowledge of the truth.
In less than eight years "The Origin of Species" has produced conviction in the minds of a majority of the most eminent living men of science. New facts, new problems, new difficulties as they arise are accepted, solved, or removed by this theory; and its principles are illustrated by the progress and conclusions of every well established branch of human knowledge.
Science moves, but slowly, slowly, creeping on from point to point. ...
Yet I doubt not through the ages one increasing purpose runs,
And the thoughts of men are widened with the process of the suns. ...
Knowledge comes, but wisdom lingers.
In our worship of certainty we must distinguish between the sound certainty and the sham, between what is gold and what is tinsel; and then, when certainty is attained, we must remember that it is not the only good; that we can buy it at too high a price; that there is danger in perpetual quiescence as well as in perpetual motion; and that a compromise must be found in a principle of growth.
The process of inner self-examination brings about a knowledge that is as rigorous and supported by evidence as anything science has to offer. At the same time, this point of view redefines faith as a knowledge that is attained not only by intellectual means, but also through the rigorous development of the emotional side of the human psyche. Such emotional knowledge is unknown to the isolated intellect and has therefore been mistakenly labeled as "irrational."
What men really want is not knowledge but certainty.
I conclude that, while it is true that science cannot decide questions of value, that is because they cannot be intellectually decided at all, and lie outside the realm of truth and falsehood. Whatever knowledge is attainable, must be attained by scientific methods; and what science cannot discover, mankind cannot know.
One need not be eminent in any part of profound knowledge in order to understand it and to apply it. The various segments of the system of profound knowledge cannot be separated. They interact with each other. For example knowledge about psychology is incomplete without knowledge of variation.
Science is not marginal. Like art, it is a universal possession of humanity, and scientific knowledge has become a vital part of our species' repertory. It comprises what we know of the material world with reasonable certainty. . . . Thanks to science and technology, access to factual information of all kinds is rising exponentially.
