The details that support the central idea that Caesar will not change his mind are:
- “But I am constant as the Northern Star” – This line directly indicates Caesar's steadfastness and his refusal to change.
- “There’s but one in all doth hold his place.” – This reinforces the idea of his unyielding nature, comparing himself to the Northern Star which remains fixed.
The other lines do not support the central idea of his unwavering position as directly as these two.
