How do individuals ethically and authentically communicate?

How do individuals of the 21st century ethically and authentically communicate? Are we communicating any less authentically because of social taboos or technological gadgets? And how is this communication helping or hindering the creation of sincere truthful relationships and societies?..And how does philosophy still hold value in a society that places such importance on pragmaticism and science?

After considering this, who do you think --Merleau-Ponty, Heidegger, or Foucault – uses philosophy or shows how philosophy deals with communicating with others authentically and ethically?
