"Guard your roving thoughts with a jealous care, for speech is but the dialer of thoughts, and every fool can plainly read in your words what is the hour of your thoughts"

In this quote, Alfred Lord Tennyson prompts care in the method we reveal our thoughts. He compares speech to a "dialer" that exposes the inner functions of our minds. Tennyson highlights the vulnerability of our thoughts, suggesting that even fools can figure out the real intentions and mindset behind our words. The quote emphasizes the need to guard our thoughts carefully, suggesting that what we state can easily betray our true emotions and ideas. Tennyson's words function as a suggestion to be mindful of our speech and conscious of the power our words hold in conveying our thoughts to others.
