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.

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.

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

Perceptual space, under its triple form, visual, tactile and motor, is essentially different from geometric space. It is neither homogeneous, nor isotropic; one can not even say that it has three dimensions. It is often said that we ‘project’ into geometric space the objects of our external perception; that we ‘localize’ them. Has this a meaning, and if so what? Does it mean that we represent to ourselves external objects in geometric space? Our representations are only the reproduction of our sensations; they can therefore be ranged only in the same frame as these, that is to say, in perceptual space. It is impossible for us to represent to ourselves external bodies in geometric space, as it is for a painter to paint on a plane canvas objects with their three dimensions. Perceptual space is only an image altered in shape by a sort of perspective, and we can represent to ourselves objects only by bringing them under the laws of this perspective. Therefore we do not represent to ourselves external bodies in geometric space, but we reason on these bodies as if they were situated in geometric space.

Love is space and time made directly perceptible to the heart.

Nothing hinders the soul’s knowledge of God as much as time and space, for time and space are fragments, whereas God is one! And therefore, if the soul is to know God, it must know him above time and outside of space; for God is neither this nor that, as are these manifold things. God is One!

Every product of technology takes up space in the mind, and requires some investment of attention that could have been used for some other purpose.

Man must understand his universe in order to understand his destiny. Mystery, however, is a very necessary ingredient in our lives. Mystery creates wonder and wonder is the basis for man’s desire to understand. Who knows what mysteries will be solved in our lifetime, and what new riddles will become the challenge of the new generations? Science has not mastered prophesy. We predict too much for next year yet far too little for the next ten. Responding to challenge is one of democracy’s great strengths. Our successes in space lead us to hope that this strength can be used in the next decade in the solution of many of our planet’s problems.

In seemingly empty space there is one Link, one Life eternal, which unites everything in the universe - animate and inanimate - one wave of Life flowing through everything.

The three dimensions of time can be regarded as the continuation of the three dimensions of space... Three-dimensionality is the function of our senses. Time is the boundary of our senses. Six-dimensional space is reality, the world as it is.

When we watch a child trying to walk, we see his countless failures; his successes are but few. If we had to limit our observations within a narrow space of time, the sight would be cruel.

The soul circumscribes all things. It contradicts all experiences. In like manner it abolishes time and space. The influence of the senses has in most men overpowered the mind to that degree that the walls of time and space have come to look real and insurmountable.

The soul is not a compensation, but a life. The soul is. Under all this running sea of circumstance, whose waters ebb and flow with perfect balance, lies the aboriginal abyss of Being. Essence, or God, is not a relation or a part, but the whole... time and space are but inverse measures of the force of the soul.

Kindness, quite simply, is the rent we must pay for the space we occupy on this planet.

The space of a needle's eye suffices for two friends, while the universe itself is not wide enough for two enemies.

As the order of the parts of time is immutable, so also is the order of the parts of space... All things are placed in time as to order of succession; and in space as to order of situation. It is from their essence or nature that they are places; and that the primary places of things should be movable, is absurd. These are therefore the absolute places; and translations out of those places, are the only absolute motions.

The Way is perfect like vast space where nothing is lacking and nothing is in excess. Indeed, it is due to our choosing to accept or reject that we do not see the true nature of things. Live neither in the entanglements of outer things, nor in the inner feeling of emptiness. Be serene in the oneness of things, nor in the inner feeling of emptiness. Be serene in the oneness of things and such erroneous views will disappear by themselves. When you try to stop activity to achieve passivity your very efforts fills you with activity. As long as you remain in one extreme or the other, you will never know Oneness.

A star is beautiful; it affords pleasure, not from what it is to do, or to give, but simply by being what it is. It befits the heavens; it has congruity with the mighty space in which it dwells. It has repose; no force disturbs its eternal peace. It has freedom; no obstruction lies between it and infinity.

Envy is a littleness of soul, which cannot see beyond a certain point, and if it does not occupy the whole space feels itself excluded.
