Fenwick stared at him, shocked. "You didn't--"

"But I did," said Baker calmly. "All very subconsciously, of course, but

I did try to commit suicide. The crystals triggered it. I'll explain how

in a minute, but since Sam Atkins was an ethical being he felt the

responsibility for what had happened to me. He had to reveal himself to

the extent of saving my life--and helping me to change so that the

suicidal drive would not appear again. He did this, but it revealed too

much of himself and destroyed the chance of completing his program. When

he gets back home, he's really going to catch hell for lousing up the

works. It's too bad."

Jim Ellerbee let out a long breath. "Sam Atkins--somebody from another

world--it doesn't seem possible. What things he could have taught us if

he'd stayed!"

Fenwick wondered why it had to have been Baker to receive this

knowledge. Baker, the High Priest of the Fixed Position, the ambassador

of Established Authority. Why couldn't Sam Atkins--or whatever his real

name might be--have whispered just a few words of light to a man willing

to listen and profit? His bowels felt sick with the impact of

opportunity forever lost.

* * * * *

"How did the crystals trigger a suicidal reaction?" asked Fenwick

finally, as if to make conversation more than anything else.

Baker's face seemed to glow. "That's the really important thing I

learned from Sam. I learned that about me--about all of us. It's hard to

explain. I experienced it--but you can only hear about it."

"We're listening," said Fenwick dully.

"I saw a picture of a lathe in a magazine a few months ago," said Baker

slowly. "You can buy one of these lathes for $174,000, if you want one.

It's a pretty fancy job. The lathe remembers what it does once, and

afterwards can do it again without any instructions.

"The lathe has a magnetic tape memory. The operator cuts the first piece

on the lathe, and the tape records all the operations necessary for that

production. After that, the operator needs only to insert the metal

stock and press the start button.

"There could be a million memories in storage, and the lathe could draw

on any one of them to repeat what it had done before at any time in its

history."

"I don't see what this has got to do with Sam and you," said Fenwick.

Baker ignored him. "A long time ago a bit of life came into existence.

It had no memory, because it was the first. But it faced the universe

and made decisions. That's the difference between life and nonlife. Did

you know that, Fenwick? The capacity to make decisions without

pre-programming. The lathe is not alive because it must be

pre-programmed by the operator. We used to say that reproduction was the

criterion of life, but the lathe could be pre-programmed to build a

duplicate of itself, complete with existing memories, if that were

desired, but that would not make it a living thing.

"Spontaneous decision. A single cell can make a simple binary choice.

Maybe nothing more complex than to be or not to be. The decision may be

conditioned by lethal circumstances that permit only a 'not' decision.

Nevertheless, a decision _is_ made, and the cell shuts down its life

processes in the very instant of death. They are not shut down for it.

"In the beginning, the first bit of life faced the world and made

decisions, and memory came into being. The structures of giant protein

molecules shifted slightly in those first cells and became a memory of

decisions and encounters. The cells split and became new pairs carrying

in each part giant patterned molecules of the same structure. These were

memory tapes that grew and divided and spread among all life until they

carried un-numbered billions of memories.

"Molecular tapes. Genes. The memory of life on earth, since the

beginning. Each new piece of life that springs from parent life comes

equipped with vast libraries of molecular tapes recording the

experiences of life since the beginning.

"Life forms as complex as mammals could not exist without this tape

library to draw upon. The bodily mechanisms could not function if they

came into existence without the taped memories out of the ages,

explaining why each organ was developed and how it should function.

Sometimes, part of the tapes _are_ missing, and the organism, if it

endures, must live without instructions for some function. One human

lifetime is too infinitesimally small to relearn procedures that have

taken aeons to develop.

"Just as the lathe operator has a choice of tapes which will cause the

lathe to function in different ways, so does new life have a choice. The

accumulated instructions and wisdom of the whole race may be available,

except for those tapes which have been lost or destroyed through the

ages. New life has a choice from that vast library of tapes. In its

inexperience, it relies on the parentage for the selection of many

proven combinations, and so we conclude certain characteristics are

'dominant' or 'inherited,' but we haven't been able to discover the

slightest reason why this is so.

"A selection of things other than color of eyes, the height of growth to

be attained, the shape of the body must also be made. A choice of modes

of facing the exterior world, a choice of stratagems to be used in

attaining survival and security in that world, must be made.

"And there is one other important factor: Mammalian life is created in a

universe where only life exists. The mammal in the womb does not know of

the existence of the external universe. Somewhere, sometime, the first

awareness of this external universe arises. In the womb. Outside the

womb. Early in fetal life, or late. When and where this awareness comes

is an individual matter. But when it comes, it arrives with lethal

impact.

"Awareness brings a million sensory invasions--chemical, physical,

extrasensory--none of them understood, all of them terrifying.

"This terrible fear that arises in this moment of awareness and

non-understanding is almost sufficient to cause a choice of death rather

than life at this point. Only because of the developed toughness,

acquired through the aeons, does the majority of mammalian life choose

to continue.

"In this moment, choices must be made as to how to cope with the

external world, how to understand it so as to diminish the fear it

inspires. The library of genetic tapes is full of possible solutions.

Parental experience is examined, too, and the very sensory impacts that

are the source of the terror are inspected to a greater or lesser extent

to see how they align with taped information.

"A very basic choice is then made. It may not be a single decision, but,

rather, a system of decisions all based on some fundamental underlying

principle. And the choice may not be made in an instant. How long a time

it may occupy I do not know.

"When the decision has been made, reaction between the individual and

the external universe begins and understanding begins to flow into the

data storage banks. As data are stored, and successful solutions found

in the encounter with the world, fear diminishes. Some kind of

equilibrium is eventually reached, in which the organism decides how

much fear it is willing to tolerate to venture farther into areas of the

unknown, and how much it is willing to limit its experience because of

this fear.

"When the decision has been made, and the point of equilibrium chosen, a

personality exists. The individual has shaped himself to face the world.

"And nothing short of a Heavenly miracle will ever change that shape!"

"You have said nothing about how the crystal caused you to attempt

suicide," said Fenwick.

"The crystal invalidated the molecular tape I had chosen to provide my

foundation program for living. The tape was completely shattered,

brought to an end. There was nothing left for me to go on."

* * * * *

"Wait a minute!" said Fenwick. "Even supposing this could happen as you

describe it, other programs could be selected out of the great number

you have described."

"Quite true. But do you know what happens to an adult human being when

the program on which his entire life is patterned is destroyed?"
