shallow thinker; indecisive person
A somewhat literary or old-fashioned term for someone who lacks depth of thought or cannot make up their mind. Not common in everyday conversation.
He is a shallow thinker, always swayed by others' opinions.
With such an indecisive attitude, it's no wonder you're called a shallow thinker.
Means 'shallow' or 'thoughtless' and is more common in modern Japanese; 不覚者 is a noun for a person with such qualities.
Compound of 不覚 (fukaku, 'lack of awareness' or 'indiscretion') and 者 (mono, 'person'). The exact historical derivation is uncertain, but the term likely emerged in literary or philosophical contexts to describe a person lacking depth or resolve.
