Pleasure is a shadow, wealth is vanity, and power a pageant; but knowledge is ecstatic in enjoyment, perennial in fame, unlimited in space, and infinite in duration. In the performance of its sacred offices, it fears no danger, spares no expense, looks in the volcano, dives into the ocean, perforates the earth, wings its flight into the skies, explores sea and land, contemplates the distant, examines the minute, comprehends the great, ascends to the sublime - no place too remote for its grasp, no height too exalted for its reach.

Opinion says hot and cold, but the reality is atoms and empty space.

In every step of the inquiry we are compelled to feel and acknowledge the immeasurable disproportion between the size of the object and the capacity of the human mind. We may strive to abstract the notions of time, of space, and of matter, which so closely adhere to all the perceptions of our experimental knowledge. But as soon as we presume to reason of infinite substance, of spiritual generation, as often as we deduce any positive conclusions from a negative idea, we are involved in darkness, perplexity, and inevitable contradiction.

Beyond a critical point within a finite space, freedom diminishes as numbers increase. ...The human question is not how many can possibly survive within the system, but what kind of existence is possible for those who do survive.

Subatomic particles are dynamic patterns which have a space aspect and a time aspect. Their space aspect makes them appear as objects with a certain mass, their time aspect as processes involving the equivalent energy… When we observe them we never see any substance; what we observe are dynamic patterns continually changing into one another – a continuous dance of energy.

The quantum field is seen as the fundamental physical entity; a continuous medium which is present everywhere in space. Particles are merely local condensations of the field; concentrations of energy which come and go, thereby losing their individual character and dissolving into the underlying field.

Sentimental time is a genuine, if poetical, version of the march of existence, even as pictorial space is a genuine, if poetical version of its distribution... the least sentimental term in sentimental time is the term now, because it marks the junction of fancy with action... For it is evident that actual succession can contain nothing but nows, so that now in a certain way is immortal. But this immortality is only a continual reiteration, a series of moments each without self-possession and without assurance of any other moment; so that if ever the now loses its indicative practical force and becomes introspective, it becomes acutely sentimental, a perpetual hope unrealized and a perpetual dying.

Policy exists in time as well as in space… a measure is correct only if it can be carried out at the proper moment.

God washes the eyes by tears until they can behold the invisible land where tears shall come no more. O love! O affliction! ye are the guides that show us the way through the great airy space where our loved ones walked; and, as hounds easily follow the scent before the dew be risen, so God teaches us, while yet our sorrow is wet, to follow on and find our dear ones in heaven.

All substances, in so far as they can be perceived to coexist in space, are in thoroughgoing reciprocity.

Every beginning is in time, and all limits to extension are in space. But space and time are in the world of sense. Consequently phenomena in the world are conditionally limited, but the world itself is not limited, either conditionally or unconditionally.

How are space, time and that which fills both, the object of sensation, possible in general? The answer is: by means of the quality of our sensibility, according to which it is affected, in its peculiar way, by objects which are in themselves unknown and quite different from those appearances.

If the subjective constitution of the senses in general were removed, the whole constitution and all the relation of objects in space and time, nay, space and time themselves, would vanish... As appearances they cannot exist in themselves but only in us. What objects are in themselves, apart from all the receptivity of our sensibility, remains completely unknown to us. We know nothing but our mode of perceiving them - a mode which is peculiar to us, and not necessarily shared in by every being.

Space and time, and with them all phenomena, are not things by themselves, but representations and cannot exist outside the mind.

Neither time nor space exists for the man who knows the eternal. Space and time are real for the an who is yet imperfect, and space is divided for him into dimensions; time, into past, present, and future.

The imagination of a boy is healthy, and the mature imagination of a man is healthy; but there is a space of life between, in which the soul is in a ferment, the character undecided, the way of life uncertain, the ambition thicksighted.

Anything which elevates the mind is sublime. Greatness of matter, space, power, virtue or beauty, are all sublime.

The state of the whole universe at any instant we believe to be the consequence of its state at the previous instant; insomuch that one who knew all the agents which exist at the present moment, their collocation in space, and all their properties, in other words, the laws of their agency, could predict the whole subsequent history of the universe, at least unless some new volition of a power capable of controlling the universe should supervene. And if any particular state of the entire universe could ever recur a second time, all subsequent states would return too, and history would, like a circulating decimal of many figures, periodically repeat itself.

Outer space is within us inasmuch as the laws of space are within us; outer and inner space are the same.

No media project succeeds based on “good news only” because good news does not trigger our alert system. Anything good indicates a safe space, the quiet background against which events can play out. The enculturated mind is cued to respond to the negative as a point of focus, which largely screens out or ignores a quiet stable base, and, because it sharpens and maintains our alert awareness, we actually begin to look for the negative.
