. . . A Friend is one who incessantly pays us the compliment of expecting from us all the virtues, and who can appreciate them in us. It takes two to speak the truth–one to speak, and another to hear. How can one treat with magnanimity mere wood and stone? If we dealt only with the false and dishonest, we should at last forget how to speak truth. . . .

In this passage, Thoreau emphasizes the significant role that genuine friendship plays in fostering truthfulness and virtuous behavior. He posits that friendship is a reciprocal relationship where both parties expect and appreciate the virtues in each other. The phrase "It takes two to speak the truth" underscores the importance of an active listener who genuinely values honesty. Without this mutual exchange, communication would be akin to addressing inanimate objects like "wood and stone," devoid of any true connection or growth in understanding. Furthermore, Thoreau cautions that constant interaction with deceitful individuals can erode one's ability to speak the truth, highlighting the necessity of surrounding oneself with sincere companions to maintain moral integrity and intellectual vitality.
