Brihat Samhita
सम्पत्त्या योजितऽदेशस्तद्विच्छिन्नकथाप्रियः । मत्तः शास्त्रएकदेशेन त्याज्यस्तादृग्महीक्षिता ॥ २-१८ ॥
One that, after the occurrence of an event, pretends that his prediction already meant so much, and one that wanders away from the subject as well as the person who is proud, having only an imperfect knowledge of the subject shall be rejected by a prince.
