Svejk expresses a critical view on the dangers of introspection and deep philosophical thinking. He suggests that when a person suddenly delves into such considerations, it can lead to irrational thoughts, likening it to the mental confusion associated with delirium tremens, a severe form of alcohol withdrawal. This reflects his belief that overthinking can have negative consequences on one's mental state.

The quote emphasizes a recurring theme in literature regarding the balance between intellectual thought and sanity. Svejk's perspective serves as a reminder that excessive reflection may drive one into mental turmoil, suggesting that a practical approach to life's challenges is often more beneficial than getting lost in abstract ideas.
