The day my son came home shaken and disturbed by something he'd read in his extended history studies, I learned something about the Human race I never ever wanted to know. After learning this fact, I couldn't find it in myself to chide him for his lack of control, for I too lost control.
Even in the days before Surak, even when driven to the greatest desperation, no Vulcan had done what the Humans had done in their ancient past. It was an aberration, an abomination. To set upon one of their own, like...I couldn't think about it. The only thing that settled me was the fact that the Humans had grown out of that strange and horrible phase of their evolution.
After my son went to the Science Academy, I decided to go on an exploratory mission aboard one of our science vessels.
Two years into the trip we came upon a small Starfleet vessel that had been stranded for many months. We rescued the crew, several of which had already died and were not to be found aboard. We had assumed that they had been given proper burials in space as was Starfleet tradition.
The ship's healer was amazed that they had survived as long as they had claimed to have gone without food. Normal humans during the same period would've starved to death long before. Her inquiries about whether they were sure about how long they had been without food were met with shakes of the head. Any questions about their deceased crewmembers were met with odd, incomprehensible looks, and silence.
When we met to discuss the matter of the crew of the rescued ship, healer T'Vask mentioned that the humans had lied about when they had last eaten. Upon hearing the healer's words, I stared in horror. It wasn't just in ancient times that this abomination took place. A thought I'd held in my mind for years changed by one word. One all important word. The others, upon seeing my reaction realized with dawning horror something I had known and refused to acknowledge:
"They eat their own."
