“In the following pages, I shall demonstrate that there exists a psychological technique by which dreams may be interpreted and that upon the application of this method every dream will show itself to be a senseful psychological structure which may be introduced into an assignable place in the psychic activity of the waking state. I shall furthermore endeavor to explain the processes which give rise to the strangeness and obscurity of the dream, and to discover through them the psychic forces, which operate whether in combination or opposition, to produce the dream. This accomplished by investigation will terminate as it will reach the point where the problem of the dream meets broader problems, the solution of which must be attempted through other material.”

The Kasîdah of Hâjî Abdû El-Yezdî (1870), Note I : Hâjî Abdû, The Man
Context: The Hâjî regrets the excessive importance attached to a possible future state: he looks upon this as a psychical stimulant, a day dream, whose revulsion and reaction disorder waking life. The condition may appear humble and prosaic to those exalted by the fumes of Fancy, by a spiritual dram-drinking which, like the physical, is the pursuit of an ideal happiness. But he is too wise to affirm or to deny the existence of another world. For life beyond the grave there is no consensus of mankind… Even the instinctive sense of our kind is here dumb. We may believe what we are taught: we can know nothing. He would, therefore, cultivate that receptive mood which, marching under the shadow of mighty events, leads to the highest of goals, — the development of Humanity. With him suspension of judgment is a system.

Context: Every interpretation is hypothetical, for it is a mere attempt to read an unfamiliar text. An obscure dream, taken by itself, can rarely be interpreted with any certainty, so that I attach little importance to the interpretation of single dreams. With a series of dreams we can have more confidence in our interpretations, for the later dreams correct the mistakes we have made m handling those that went before. We are also better able, in a dream series, to recognize the important contents and basic themes.

Lecture II: Of Free Inquiry, considered as a Means for obtaining Just Knowledge
A Course of Popular Lectures (1829)
Context: However novel it may appear, I shall venture the assertion that until women assume the place in society which good sense and good feeling alike assign to them, human improvement must advance but feebly. It is in vain that we would circumscribe the power of one half of our race, and that half by far the most important and influential. If they exert it not for good they will for evil, if they advance not knowledge they will perpetuate ignorance. Let women stand where they may in the scale of improvement, their position decides that of the race.

Context: How do I know that enjoying life is not a delusion? How do I know that in hating death we are not like people who got lost in early childhood and do not know the way home? Lady Li was the child of a border guard in Ai. When first captured by the state of Jin, she wept so much her clothes were soaked. But after she entered the palace, shared the king's bed, and dined on the finest meats, she regretted her tears. How do I know that the dead do not regret their previous longing for life? One who dreams of drinking wine may in the morning weep; one who dreams weeping may in the morning go out to hunt. During our dreams we do not know we are dreaming. We may even dream of interpreting a dream. Only on waking do we know it was a dream. Only after the great awakening will we realize that this is the great dream. And yet fools think they are awake, presuming to know that they are rulers or herdsmen. How dense! You and Confucius are both dreaming, and I who say you are a dream am also a dream. Such is my tale. It will probably be called preposterous, but after ten thousand generations there may be a great sage who will be able to explain it, a trivial interval equivalent to the passage from morning to night.
