Character: Dr. Salvatore

I was afraid that my invention, in the conditions of our social order, would do more harm than good. A struggle has already begun around Ichthyander. Who denounced me out of revenge? Here is this Zurita who stole Ichthyander from me. And the generals and admirals would have taken away Zurit Ichthyander, what good, in order to force the amphibious man to sink warships. No, I could not make Ichthyander and the "Ichthyanders" common property in a country where struggle and greed turn the highest discoveries into evil, increasing the amount of human suffering.

In the ocean of life everywhere - from the equator to the poles, from the surface to the depth of nearly ten kilometres.

The man is not perfect.

Struggle and greed pay higher opening in evil, by increasing the sum of human suffering.

Silence is Golden.

The trouble is not that man evolved from animal, and that he never ceased to be an animal... Rude, angry, unreasonable.
