A Quote by Pierre-Simon Laplace
We are so far from knowing all the forces of nature and their various modes of action that it would be unworthy of the philosopher to deny phenomena simply because they are inexplicable at the present state of our knowledge. The more difficult it is to acknowledge their existence, the greater the care with which we must study these phenomena.

Our present work sets forth mathematical principles of philosophy. For the basic problem of philosophy seems to be to discover the forces of nature from the phenomena of motions and then to demonstrate the other phenomena from these forces. It is to these ends that the general propositions in books 1 and 2 are directed, while in book 3 our explanation of the system of the world illustrates these propositions.
Our design, not respecting arts, but philosophy, and our subject, not manual, but natural powers, we consider chiefly those things which relate to gravity, levity, elastic force, the resistance of fluids, and the like forces, whether attractive or impulsive; and therefore we offer this work as mathematical principles of philosophy; for all the difficulty of philosophy seems to consist in this from the phenomena of motions to investigate the forces of nature, and then from these forces to demonstrate the other phenomena.
I do not deny God, because that word conveys to me no idea, and I cannot deny that which presents to me no distinct affirmation, and of which the would-be affirmer has no conception. I cannot war with a nonentity. If, however, God is affirmed to represent an existence which is distinct from the existence of which I am a mode, and which it is alleged is not the noumenon of which the word I represents only a speciality of phenomena, then I deny God, and affirm that it is impossible God can be.
In the final, the positive, state, the mind has given over the vain search after absolute notions, the origin and destination of the universe, and the causes of phenomena, and applies itself to the study of their laws - that is, their invariable relations of succession and resemblance. Reasoning and observation, duly combined, are the means of this knowledge. What is now understood when we speak of an explanation of facts is simply the establishment of a connection between single phenomena and some general facts.
A poet must be a psychologist, but a secret one: he should know and feel the roots of phenomena but present only the phenomena themselves in full bloom or as they fade away.
Each thing that exists remains forever, and that very existence of existence is proof of its eternity. But without that realization, which is the knowledge of perfect being, man would never know whether there was existence or non-existence. If eternal existence is altered, then it must become more beautiful; and if it disappears, it must return with more sublime image; and if it sleeps, it must dream of a better awakening, for it is ever greater upon its rebirth.
Atheism is based upon a materialist philosophy, which holds that nothing exists but natural phenomena. There are no supernatural forces or entities, nor can there be any. Nature simply exists.
Finding meaning in global mass phenomena can be difficult because the phenomena themselves are invisible, spread across the earth in millions of separate places. There is no Mount Everest of waste that we can make a pilgrimage to and behold the sobering aggregate of our discarded stuff, seeing and feeling it viscerally with our senses.
Our alleged facts might be true in all kinds of ways without contradicting any truth already known. I will dwell now on only one possible line of explanation, - not that I see any way of elucidating all the new phenomena I regard as genuine, but because it seems probable I may shed a light on some of those phenomena. All the phenomena of the universe are presumably in some way continuous; and certain facts, plucked as it were from the very heart of nature, are likely to be of use in our gradual discovery of facts which lie deeper still.
The identification of the genes which determine biological phenomena and the study of the control they exert on these phenomena has proven to be the most successful approach to a detailed understanding of the mechanism of biological processes.
I know that certain minds would regard as audacious the idea of relating the laws which preside over the play of our organs to those laws which govern inanimate bodies; but, although novel, this truth is none the less incontestable. To hold that the phenomena of life are entirely distinct from the general phenomena of nature is to commit a grave error, it is to oppose the continued progress of science.
It would appear... that moral phenomena, when observed on a great scale, are found to resemble physical phenomena; and we thus arrive, in inquiries of this kind, at the fundamental principle, that the greater the number of individuals observed, the more do individual peculiarities, whether physical or moral, become effaced, and leave in a prominent point of view the general facts, by virtue of which society exists and is preserved.
The next day the Indian told me their name for this light,--artoosoq',--and on my inquiring concerning the will-o'-the-wisp, and the like phenomena, he said that his "folks" sometimes saw fires passing along at various heights, even as high as the trees, and making a noise. I was prepared after this to hear of the most startling and unimagined phenomena, witnessed by "his folks"; they are abroad at all hours and seasons in scenes so unfrequented by white men. Nature must have made a thousand revelations to them which are still secrets to us.
[The sceptic] must acknowledge, if he will acknowledge any thing, that all human life must perish, were his principles to prevail.All discourse, all action would immediately cease, and men remain in a total lethargy, till the necessities of nature, unsatisfied, put an end to their miserable existence.
It will be found that everything depends on the composition of the forces with which the particles of matter act upon one another; and from these forces, as a matter of fact, all phenomena of Nature take their origin.
It would not become physical science to see in its self created, changeable, economical tools, molecules and atoms, realities behind phenomena... The atom must remain a tool for representing phenomena.
