"IT is difficult to speak or write with becoming moderation or propriety, on topics to which we are biased by prejudice, interest, or even principle"

Joseph Lancaster's quote addresses a profound challenge in human interaction: the trouble of attaining small amounts and propriety when going over topics that touch upon our predispositions and deeply held beliefs. At its core, this statement acknowledges that our perspectives are typically clouded by subjective impacts such as bias, personal interest, or principled stands, which can distort our capability to communicate objectively and fairly.

The inclusion of "bias" mean preconceived notions or predispositions that alter our understanding of truth. Such predispositions can be deeply deep-rooted, often even automatically affecting how we analyze details and participate in discourse. This makes the pursuit of small amounts-- a well balanced, fair-minded technique-- an intricate endeavor, as these prejudices frequently operate below the surface of our awareness.

Meanwhile, "interest" recommends that personal or vested interests can cause partiality. When our self-interest is at stake, we might consciously or automatically prioritize our results over a fair discourse. This serves as a barrier to moderation, as it can trigger us to safeguard our position strongly, often at the expenditure of reality or fairness.

The mention of "concept" might appear paradoxical. Concepts, after all, are frequently viewed as ethical or moral compasses. However, unwavering adherence to concepts can also cloud judgment, specifically if those concepts lead us to dismiss alternative viewpoints. In such cases, principled positions can transform into ideological rigidness, more complicating the goal for small amounts in conversations.

Therefore, Lancaster's observation emphasizes the need for self-awareness and crucial reflection. It calls for a mindful effort to recognize and alleviate our biases, to strive for neutrality, and to be open to differing point of views. Only through this alert self-examination can we hope to take part in conversations marked by real small amounts and propriety, fostering discussions that are not only sincere but also empathetic and inclusive.
