This quote suggests that the people we label as enemies or adversaries often embody characteristics that we dislike or deny in ourselves. This concept is rooted in the psychological theory of the shadow self, a term coined by Carl Jung, which refers to the unconscious aspects of the personality that the conscious ego does not identify with. These aspects can be negative or positive, and they’re typically suppressed or ignored. The “enemy” is seen as an exaggerated reflection of these suppressed aspects, forcing us to confront what we’d rather ignore about ourselves.

In simpler terms, we tend to dislike in others what we cannot accept in ourselves. For example, if we have an issue with someone who is overly assertive, it may be because we struggle with assertiveness ourselves and envy or resent them for it. Or perhaps we too are assertive, but we view it as a negative trait and suppress it, leading us to dislike it when we see it in others.

In today’s world, this idea can be applied in various ways. For instance, in the realm of politics or social issues, the people we strongly disagree with or even despise might reflect the extreme versions of our own fears, biases, or prejudices. Recognizing this can lead to greater self-awareness and empathy, reducing polarization and hostility.

In terms of personal development, understanding this concept can lead to significant growth. By acknowledging and confronting our shadow selves, we can understand our reactions and feelings towards others better. This can help us improve our relationships, as we learn to separate our own issues from those of the people around us. It can also promote self-acceptance and self-improvement, as we learn to recognize and work on our weaknesses rather than projecting them onto others.
