"Abuse of words has been the great instrument of sophistry and chicanery, of party, faction, and division of society"

In this quote, John Adams is highlighting the harmful power of controling language for personal gain. He refers to the "abuse of words" as a tool utilized by those who take part in sophistry (the use of smart but incorrect arguments) and chicanery (deceptiveness or trickery) to enhance their own programs. Adams suggests that this control of language has been a significant contributor to the department and conflict within society, perpetuated by political celebrations and factions. By distorting the meaning of words and utilizing them to misinform and deceive, people and groups can sow discord and develop departments within society. Adams cautions against the abuse of words and the requirement for truthful and truthful interaction in order to preserve a harmonious and just society.
