The Kalama Sutta (AN 3.65) says:
So, as I said, Kalamas: 'Don't go by reports, by legends, by traditions, by scripture, by logical conjecture, by inference, by analogies, by agreement through pondering views, by probability, or by the thought, "This contemplative is our teacher." When you know for yourselves that, "These qualities are unskillful; these qualities are blameworthy; these qualities are criticized by the wise; these qualities, when adopted & carried out, lead to harm & to suffering" — then you should abandon them.' Thus was it said. And in reference to this was it said.
Now, Kalamas, don't go by reports, by legends, by traditions, by scripture, by logical conjecture, by inference, by analogies, by agreement through pondering views, by probability, or by the thought, 'This contemplative is our teacher.' When you know for yourselves that, 'These qualities are skillful; these qualities are blameless; these qualities are praised by the wise; these qualities, when adopted & carried out, lead to welfare & to happiness' — then you should enter & remain in them.
I think that implies you should care about and understand, as well as "know for yourself", what wise people think.
I think there's a lot of mention too, in the suttas, about social harmony within the sangha -- and its being important to have good or spiritual friends -- I think that might be what's meant by "the holy life" (brahamacariya):
Not so, Ānanda! Not so, Ānanda!
“Mā hevaṃ, ānanda, mā hevaṃ, ānanda.
Good friends, companions, and associates are the whole of the spiritual life.
Sakalamevidaṃ, ānanda, brahmacariyaṃ, yadidaṃ—kalyāṇamittatā kalyāṇasahāyatā kalyāṇasampavaṅkatā.
We also have precepts (e.g. to be harmless). They too are motivated by what other people think:
All tremble at violence; all fear death. Putting oneself in the place of another, one should not kill nor cause another to kill.
