To "deny the concept of death" refers to rejecting or refusing to accept the idea that death is an inevitable and universal part of life. It suggests an unwillingness to acknowledge the reality of mortality, often stemming from a fear or discomfort associated with contemplating one's own death or the finality of life. People who deny the concept of death may adopt various coping mechanisms or belief systems to rationalize or avoid facing the idea of their own or others' mortality.
