The right answer is the following:
Foolish and cowardly
We can notice that reading an extract from the poem that I have reported below:
“When I think I am clever, the fool in me speaks. When I am ready to be courageous, a thousand reservations reveal the coward that I also am.”
Neruda is looking for something in the others person that he couldn’t find in himself , it’s like a lack of something that he sees in other people and he admires it. The title “We are many” refers to this concept too, he quite often ask for how many different “I” are within himself and it is a clear example of the influence of the others in our lives. How the others can be part of our unconscious behavior.
