Mark nodded even though she couldn't see. He'd suddenly lost any desire to talk, and his plans for a perfect day washed away with the stream. The memories. They never let him go, not even for a half hour. They always had to rush back in, bringing all the horror.
Concepts of memory tend to reflect the technology of the times. Plato and Aristotle saw memories as thoughts inscribed on wax tablets that could be erased easily and used again. These days, we tend to think of memory as a camera or a video recorder, filming, storing, and recycling the vast troves of data we accumulate throughout our lives. In practice, though, every memory we retain depends upon a chain of chemical interactions that connect millions of neurons to one another. Those neurons never touch; instead, they communicate through tiny gaps, or synapses, that surround each of them. Every neuron has branching filaments, called dendrites, that receive chemical signals from other nerve cells and send the information across the synapse to the body of the next cell. The typical human brain has trillions of these connections. When we learn something, chemicals in the brain strengthen the synapses that connect neurons. Long-term memories, built from new proteins, change those synaptic networks constantly; inevitably, some grow weaker and others, as they absorb new information, grow more powerful.

He felt more crypts cracking open inside of him; the stench he smelled was not decayed bodies but decayed memories, and that was somehow worse.
Though denigrated by some outside academia and research, she embraced knowledge for its own sake and what better way to honor that than reveling in the intricacies of the brain? If there were any answers to the human condition, if an immortal soul made its home anywhere, it was in its spongy gray folds.
A mind is a simulation that simulates itself.

A typical Celestine will devote a large proportion of their time to passing through the inscribed sectors of the planet studying the writings, either alone or accompanied by companions with whom to share comments. This is a favourite pastime among them, and as they travel towards the boundaries of the inscribed regions they can watch the ongoing work of those Celestines that have been chosen to record their ideas _ tirelessly twisting, pausing to gather energy, then exerting themselves again; painstakingly working the same patch of dust several thousand times over to shape each individual furrow; to capture, symbol by symbol, the knowledge they have contributed to the Celestine corpus. There is great pride and precision, as well as immense labour, in their toil. Before they commence work, the piece of ground that will house the writing will be chosen very carefully for its aspect. Then, the most favourable angle to the light will be calculated, for the orientation of the wording. The language used is of the most poetic and grandiose sort, quite different from the vernacular, and the symbols themselves are embellished with flourishes, extravagances and curlicues that are unique to the creator. Celestines love to observe this work, which constitutes the pinnacle of their art and of their ceaseless thought-endeavours, and embodies their very reason for being.
