Eating, Sleep, Fear and Sex ; these habits are common between human beings and animals. It is the Dharma which is the special quality of the human beings. Without the Dharma, they are similar to the animals.
Rama is The Embodiment Of Dharma.
Maaricha, while speaking to Ravana- (Aranya Kandam 37-13):
रामो विग्रहवान् धर्मः साधुः सत्य पराक्रमः | राजा सर्वस्य लोकस्य देवानाम् इव वासवः || ३-३७-१३||
The difference between evidence that something is absent (e.g., an observation that suggests there were no dragons here today) and simple absence of evidence (e.g., no careful research has been done) can be nuanced.
Indeed, scientists will often debate whether an experiment's result should be considered evidence of absence, or if it remains absence of evidence. The debate is whether the experiment would have detected the phenomenon of interest if it was there.
