When ideas change your thoughts, that is philosophy. When God changes your thoughts, that is faith. When facts change your thoughts, that is science. When a person has neither ideas nor religious beliefs, and ignores facts, stay away from him and do not waste your precious time, because philosophy refines reason, faith settles ultimate concerns, and science verifies reality. When a person actively closes the door to these three realms, he simultaneously abandons rational thinking, transcendental pursuit, and empirical verification. This is like building an indestructible cognitive prison for oneself, rejecting all possibilities of internal and external information exchange, and his thoughts will inevitably become rigid and exhausted.
