Calculating people are contemptable. The reason for this is that calculation deals with loss and gain, and the loss and gain mind never stops. Death is considered loss and life is considered gain. Thus, death is something that such a person does not care for, and he is contemptable.
Furthermore, scholars and their like are men who with wit and speech hide their own true cowardice and greed. People often misjudge this.
