Which words in this excerpt from Homer’s Odyssey show how Ulysses thinks of the Cyclops as different from a civilized group like the Greeks?

The land of Cyclops first, a savage kind,
Nor tamed by manners, nor by laws confined:
Untaught to plant, to turn the glebe, and sow,
They all their products to free nature owe:
The soil, untill'd, a ready harvest yields,
With wheat and barley wave the golden fields;
Spontaneous wines from weighty clusters pour,
And Jove descends in each prolific shower,
By these no statues and no rights are known,
No council held, no monarch fills the throne;
But high on hills, or airy cliffs, they dwell,
Or deep in caves whose entrance leads to hell.
Each rules his race, his neighbour not his care,
Heedless of others, to his own severe.
