I like to deal with EVERY aspect of our condition, and that means terror and humor in equal mix. Some books have more room for humor than others.

Koontz is describing an artistic credo: he aims to portray the full range of human experience rather than confining himself to a single emotional register. By pairing “terror and humor,” he suggests that fear and laughter are not opposites so much as neighboring responses to vulnerability, uncertainty, and mortality. The remark also implies a practical, book-by-book calibration: the subject matter and narrative situation determine how much comic relief can be integrated without breaking tone. In this view, humor is not merely a garnish but a tool for realism and contrast—heightening dread by relief, and making characters feel more recognizably human under pressure.
