I know that I have lived because I have felt, and, feeling giving me the knowledge of my existence, I know likewise that I shall exist no more when I shall have ceased to feel.

Giacomo Casanova’s quote reflects his deep contemplation of existence and feeling as central to understanding life and death. He asserts that his knowledge of life comes from his ability to feel, as feeling gives him a sense of his own existence. For Casanova, the act of feeling—whether through love, passion, or other human experiences—connects him to his sense of self. The quote suggests that awareness of life is intimately tied to emotional and sensory experiences, and through those experiences, we gain the knowledge of being alive.

Casanova further implies that the cessation of feeling will lead to the cessation of existence itself. In this sense, he connects emotions and sensory perception to the essence of being. The loss of feeling, in Casanova’s view, would signify the loss of consciousness and, by extension, the end of one’s existence. This perspective aligns with a philosophical view that life and the self are not separate from our emotional experiences but are fundamentally intertwined with them.

The quote speaks to Casanova’s often passionate approach to life, particularly in the areas of love and sensual pleasure. Known for his numerous love affairs and adventurous lifestyle, Casanova believed that these experiences defined him and gave meaning to his life. His reflection here could be interpreted as an acceptance that, without the ability to feel, life loses its vitality and meaning, leading to death. In this way, his thoughts on existence are deeply rooted in the physical and emotional aspects of human life.

The origin of the quote lies in Casanova's memoirs and his introspective writings, where he frequently pondered the nature of life, love, and death. As a man who lived a life filled with intense emotions and experiences, his words reflect both his personal philosophy and his attempt to reconcile the transient nature of life with his intense experiences of feeling. His exploration of existence and death became a cornerstone of his broader reflections on human nature and the significance of living fully.
