The kanji 敦 is a phono-semantic compound (形声文字). The left side is a radical called "攴(ぼく)" which indicates "action" or "to tap." The right side is "享(きょう)" which originally represented a type of offering. So, the character 敦 combines the ideas of offering and action and originally meant "to offer respectfully." Over time, the meaning evolved to encompass the qualities of sincerity, thickness, and kindness.
