“There is no reality, only perception.”

“There are things known and there are things unknown, and in between are the doors of perception.”
Aldous Huxley, using the term "the doors of perception" which originated with William Blake in The Marriage of Heaven and Hell. It is sometimes credited to Morrison because he cited it in interviews as the inspiration for the name The Doors and without always crediting Huxley as the source.

Si rinunci per moda, per smania di novità, per affettazione di scienza, si rinneghi l'arte nostra, il nostro istinto, quel nostro fare sicuro spontaneo naturale sensibile abbagliante di luce, è assurdo e stupido.

Philosophiae Naturalis Principia Mathematica (1687), Scholium Generale (1713; 1726)
Context: This Being governs all things, not as the soul of the world, but as Lord over all: And on account of his dominion he is wont to be called Lord God παντοκρáτωρ or Universal Ruler. For God is a relative word, and has a respect to servants; and Deity is the dominion of God, not over his own body, as those imagine who fancy God to be the soul of the world, but over servants. The supreme God is a Being eternal, infinite, absolutely perfect; but a being, however perfect, without dominion, cannot be said to be Lord God; for we say, my God, your God, the God of Israel, the God of Gods, and Lord of Lords; but we do not say, my Eternal, your Eternal, the Eternal of Israel, the Eternal of Gods; we do not say, my Infinite, or my Perfect: These are titles which have no respect to servants. The word God usually signifies Lord; but every lord is not a God. It is the dominion of a spiritual being which constitutes a God; a true, supreme or imaginary dominion makes a true, supreme or imaginary God. And from his true dominion it follows, that the true God is a Living, Intelligent and Powerful Being; and from his other perfections, that he is Supreme or most Perfect. He is Eternal and Infinite, Omnipotent and Omniscient; that is, his duration reaches from Eternity to Eternity; his presence from Infinity to Infinity; he governs all things, and knows all things that are or can be done. He is not Eternity or Infinity, but Eternal and Infinite; he is not Duration or Space, but he endures and is present. He endures for ever, and is every where present; and by existing always and every where, he constitutes Duration and Space. Since every particle of Space is always, and every indivisible moment of Duration is every where, certainly the Maker and Lord of all things cannot be never and no where. Every soul that has perception is, though in different times and in different organs of sense and motion, still the same indivisible person. There are given successive parts in duration, co-existant parts in space, but neither the one nor the other in the person of a man, or his thinking principle; and much less can they be found in the thinking substance of God. Every man, so far as he is a thing that has perception, is one and the same man during his whole life, in all and each of his organs of sense. God is the same God, always and every where. He is omnipresent, not virtually only, but also substantially; for virtue cannot subsist without substance. In him are all things contained and moved; yet neither affects the other: God suffers nothing from the motion of bodies; bodies find no resistance from the omnipresence of God. 'Tis allowed by all that the supreme God exists necessarily; and by the same necessity he exists always and every where. Whence also he is all similar, all eye, all ear, all brain, all arm, all power to perceive, to understand, and to act; but in a manner not at all human, in a manner not at all corporeal, in a manner utterly unknown to us. As a blind man has no idea of colours, so have we no idea of the manner by which the all-wise God perceives and understands all things. He is utterly void of all body and bodily figure, and can therefore neither be seen, nor heard, nor touched; nor ought to be worshipped under the representation of any corporeal thing. We have ideas of his attributes, but what the real substance of any thing is, we know not. In bodies we see only their figures and colours, we hear only the sounds, we touch only their outward surfaces, we smell only the smells, and taste the favours; but their inward substances are not to be known, either by our senses, or by any reflex act of our minds; much less then have we any idea of the substance of God. We know him only by his most wise and excellent contrivances of things, and final causes; we admire him for his perfections; but we reverence and adore him on account of his dominion. For we adore him as his servants; and a God without dominion, providence, and final causes, is nothing else but Fate and Nature. Blind metaphysical necessity, which is certainly the same always and every where, could produce no variety of things. All that diversity of natural things which we find, suited to different times and places, could arise from nothing but the ideas and will of a Being necessarily existing. But by way of allegory, God is said to see, to speak, to laugh, to love, to hate, to desire, to give, to receive, to rejoice, to be angry, to fight, to frame, to work, to build. For all our notions of God are taken from the ways of mankind, by a certain similitude which, though not perfect, has some likeness however. And thus much concerning God; to discourse of whom from the appearances of things, does certainly belong to Natural Philosophy.

Context: Solve all your problems through meditation. Exchange unprofitable religious speculations for actual God-contact. Clear your mind of dogmatic theological debris; let in the fresh, healing waters of direct perception. Attune yourself to the active inner Guidance; the Divine Voice has the answer to every dilemma of life. Though man's ingenuity for getting himself into trouble appears to be endless, the Infinite Succor is no less resourceful.

On Truth and Lie in an Extra-Moral Sense (1873)

Letter to Markus Fierz (1948)
Context: What now is the answer to the question as to the bridge between the perception of the senses and the concepts, which is now reduced to the question as to the bridge between the outer perceptions and those inner image-like representations. It seems to me one has to postulate a cosmic order of nature — outside of our arbitrariness— to which the outer material objects are subjected as are the inner images... The organizing and regulating has to be posited beyond the differentiation of physical and psychical... I am all for it to call this "organizing and regulating" "archetypes." It would then be inadmissible to define these as psychic contents. Rather, the above-mentioned inner pictures (dominants of the collective unconscious, see Jung) are the psychic manifestations of the archetypes, but which would have to produce and condition all nature laws belonging to the world of matter. The nature laws of matter would then be the physical manifestation of the archetypes.

"On the Physiological Causes of Harmony" (1857), p. 81
Popular Lectures on Scientific Subjects (1881)
Context: As you are aware, no perceptions obtained by the senses are merely sensations impressed on our nervous systems. A peculiar intellectual activity is required to pass from a nervous sensation to the conception of an external object, which the sensation has aroused. The sensations of our nerves of sense are mere symbols indicating certain external objects, and it is usually only after considerable practice that we acquire the power of drawing correct conclusions from our sensations respecting the corresponding objects.

Pupils at Sais (1799)
Context: Over his own heart and his own thoughts he watched attentively. He knew not whither his longing was carrying him. As he grew up, he wandered far and wide; viewed other lands, other seas, new atmospheres, new rocks, unknown plants, animals, men; descended into caverns, saw how in courses and varying strata the edifice of the Earth was completed, and fashioned clay into strange figures of rocks. By and by, he came to find everywhere objects already known, but wonderfully mingled, united; and thus often extraordinary things came to shape in him. He soon became aware of combinations in all, of conjunctures, concurrences. Erelong, he no more saw anything alone. — In great variegated images, the perceptions of his senses crowded round him; he heard, saw, touched and thought at once. He rejoiced to bring strangers together. Now the stars were men, now men were stars, the stones animals, the clouds plants; he sported with powers and appearances; he knew where and how this and that was to be found, to be brought into action; and so himself struck over the strings, for tones and touches of his own.
