“Man's quest for knowledge is an expanding series whose limit is infinity, but philosophy seeks to attain that limit at one blow, by a short circuit providing the certainty of complete and inalterable truth. Science meanwhile advances at its gradual pace, often slowing to a crawl, and for periods it even walks in place, but eventually it reaches the various ultimate trenches dug by philosophical thought, and, quite heedless of the fact that it is not supposed to be able to cross those final barriers to the intellect, goes right on.”

“In order to complete the history of the human mind, and attain to a perfect knowledge of its nature and operations, we must contemplate man in all those various situations wherein he has been placed. We must follow him in his progress through the different stages of society, as he gradually advances from the infant state of civil life toward its maturity and decline.”

William Robertson (historian) (1721–1793) Scottish historian, minister of religion, and Principal of the University of Edinburgh

“As long as algebra and geometry proceeded along separate paths, their advance was slow and their applications limited. But when these sciences joined company, they drew from each other fresh vitality and thenceforward marched on at a rapid pace toward perfection.”

“A geologist should be well versed in chemistry, natural philosophy, mineralogy, zoology, comparative anatomy, botany; in short, in every science relating to organic and inorganic nature. …But the brief duration of human life, and our limited powers, are so far from permitting us to aspire to such extensive acquisitions, that excellence even in one department is within the reach of few, and those individuals most effectually promote the general progress, who concentrate their thoughts on a limited portion of the field of inquiry.”

“Now this structure of hope (among other things) is also what distinguishes philosophy from the special sciences. There is a relationship with the object that is different in principle in the two cases. The question of the special sciences is in principle ultimately answerable, or, at least, it is not un-answerable. It can be said, in a final way (or some day, one will be able to say in a final way) what is the cause, say, of this particular infectious disease. It is in principle possible that one day someone will say, "It is now scientifically proven that such and such is the case, and no otherwise." But […] a philosophical question can never be finally, conclusively answered. […] The object of philosophy is given to the philosopher on the basis of a hope. This is where Dilthey's words make sense: "The demands on the philosophizing person cannot be satisfied. A physicist is an agreeable entity, useful for himself and others; a philosopher, like the saint, only exists as an ideal." It is in the nature of the special sciences to emerge from a state of wonder to the extent that they reach "results." But the philosopher does not emerge from wonder.
Here is at once the limit and the measure of science, as well as the great value, and great doubtfulness, of philosophy. Certainly, in itself it is a "greater" thing to dwell "under the stars."”

Josef Pieper (1904–1997) German philosopher

But man is not made to live "out there" permanently! Certainly, it is a more valuable question, as such, to ask about the whole world and the ultimate nature of things. But the answer is not as easily forthcoming as for the special sciences!
