In the Autumn of 1994, I was a student at UC Irvine Studio Art. One day when I was writing my diary with the pen that has traveled with me for years, I found discontinuous lines spewing out of its nib. I realized that the pen has traveled to the end of its life. Therefore, I took a piece of letter size paper, and started to doodle in irregular directions with the pen until the ink was exhausted. This was the birth of The Last Drawing of His Life, the first work in the Pen Walking series. I later wrote a poem describing this experience. In this poem, I visit a personified pen, who, as death nears him, asks me to give him a hand and help him to draw the last drawing of his life. The strokes on the paper reveal the past we have experienced together, the plans we have drawn up, and even the smallest affection we have for each other. Until the very end of the drawing, where the end is also the beginning, the pen stops at where he set off and could not journey anymore. And this was the birth of the prose The Last Drawing of His Life.

To create the "Pen Walking" paintings, SHI uses one or multiple pencils, adhering the pencil shavings to paper upon completion. These shavings symbolize the remnants of a life concluded, while the spent pencils represent life's endless, often unpredictable cycle. The marks left by the pen are akin to life's deeds, and the pencil's exhaustion, the destiny of the human flesh.

Each pencil represents a cycle of life, and a panoramic view of one's existence leads to a sigh of existential emptiness: "No matter what, it all comes down to this."

1994年秋天，當時我在美國加州大學爾灣分校念書。有一天，在我寫日記的時候，手中那支伴我旅行多年的筆漸漸寫畫出斷斷續續的線條，我知道它已經快到了它生命的盡頭。於是我拿出一張美國信紙尺寸的白紙，不規則地塗畫走線，直到筆水用盡才停止動作。這就是第一件的走筆作品〈生命中最後的一張畫〉。後來，針對這個經驗，我以擬人化的手法寫了一首詩，大意是去看望一位來日無多的知己－筆，他要我撐起他，幫助他完成生命中最後的一張畫。畫中的筆觸流露出我們共同經歷的過去，共同計劃的方案、草圖，乃至彼此心中幽微的點滴⋯。直到最後，終點又是起點，他停在起筆的地方，再也不動了。這就是〈生命中最後的一張畫〉詩文版的由來。

在創作《走筆》系列畫作時，石晉華耗盡一枝或多枝鉛筆，並將鉛筆屑黏貼於紙上以完成作品。這些鉛筆屑象徵著生命終結後的殘骸，而鉛筆的耗損則代表著生命無常的循環。筆觸的痕跡如同人生的作為，鉛筆的耗盡，則是肉體無常的宿命。

一枝枝的筆，代表一生生的輪迴，而全覽的一生，使人喟嘆虛無人生：「不論再怎麼樣，也不過如此」。
