soul of man.”
“I’m a biologist. I save lives … not souls.”
“Well, I can assure you that saving lives will become increasingly difficult in the coming years. Overpopulation breeds far more than spiritual discontent. There is a passage in Machiavelli—”
“Yes,” she interrupted, reciting her recollection of the famous quote. “ ‘When every province of the world so teems with inhabitants that they can neither subsist where they are nor remove themselves elsewhere … the world will purge itself.’ ” She stared up at him. “All of us at the WHO are familiar with that quotation.”
“Good, then you know that Machiavelli went on to talk about plagues as the world’s natural way of self-purging.”
“Yes, and as I mentioned in my talk, we are well aware of the direct correlation between population density and the likelihood of wide-scale epidemics, but we are constantly devising new detection and treatment methods. The WHO remains confident that we can prevent future pandemics.”
“That’s a pity.”
Elizabeth stared in disbelief. “I beg your pardon?!”
“Dr. Sinskey,” the man said with a strange laugh, “you talk about controlling epidemics as if it’s a good thing.”
She gaped up at the man in mute disbelief.
“There you have it,” the lanky man declared, sounding like an attorney resting his case. “Here I stand with the head of the World Health Organization—the best the WHO has to offer. A terrifying thought if you consider it. I have shown you this image of impending misery.” He refreshed the screen, again displaying the image of the bodies. “I have reminded you of the awesome power of unchecked population growth.” He pointed to his small stack of paper. “I have enlightened you about the fact that we are on the brink of a spiritual collapse.” He paused and turned directly toward her. “And your response? Free condoms in Africa.” The man gave a derisive sneer. “This is like swinging a flyswatter at an incoming asteroid. The time bomb is no longer ticking. It has already gone off, and without drastic measures, exponential mathematics will become your new God … and ‘He’ is a vengeful God. He will bring to you Dante’s vision of hell right outside on Park Avenue … huddled masses wallowing in their own excrement. A global culling orchestrated by Nature herself.”
“Is that so?” Elizabeth snapped. “So tell me, in your vision of a sustainable future, what is the ideal population of earth? What is the magic number at which humankind can hope to sustain itself indefinitely … and in relative comfort?”
The tall man smiled, clearly appreciating the question. “Any environmental biologist or statistician will tell you that humankind’s best chance of long-term survival occurs with a global population of around four billion.”
“Four billion?” Elizabeth fired back. “We’re at seven billion now, so it’s a little late for that.”
The tall man’s green eyes flashed fire. “Is it?”
CHAPTER 23
Robert Langdon landed hard on the spongy earth just inside the retaining wall of the Boboli Gardens’ heavily wooded southern edge. Sienna landed beside him and stood up, brushing herself off and taking in their surroundings.
They were standing in a glade of moss and ferns on the edge of a small forest. From here, the Palazzo Pitti was entirely obscured from view, and Langdon sensed they were about as far from the palace as one could get in the gardens. At least there were no workers or tourists out this far at this early hour.
Langdon gazed at a peastone pathway that wound gracefully downhill into the forest before them. At the point where the path disappeared into the trees, a marble statue had been perfectly situated to receive the eye. Langdon was not surprised. The Boboli Gardens had enjoyed the exceptional design talents of Niccolò Tribolo, Giorgio Vasari, and Bernardo Buontalenti—a brain trust of aesthetic talent that had created on this 111-acre canvas a walkable masterpiece.
“If we head northeast, we’ll reach the palace,” Langdon said, pointing down the path. “We can mix there with the tourists and exit unseen. I’m guessing it opens at nine.”
Langdon glanced down to check the time but saw only his bare wrist where his Mickey Mouse watch had once been strapped. He wondered absently if it was still at the hospital with the rest of his clothing and if he’d ever be able to retrieve it.
Sienna planted her feet defiantly. “Robert, before we take another step, I want to know where we’re going. What did you figure out back there? The Malebolge? You said it was out of sequence?”
Langdon motioned toward a wooded area
