Between silence and speech, silence is more dangerous: it's very safety endangers the self

For example, we say that one regrets ten times for having spoken to once for having kept silent - and why? Because the external fact of having spoken can involve one in difficulties, since it is an actuality.  But to have kept silent!  And yet this is the most dangerous of all . . . Not to venture is prudent.  And yet, precisely by not venturing it is so terribly easy to lose what would be hard to lose, however much one lost by risking, and in any case never this way, so easily, so completely, as if it were nothing at all - namely, oneself. - Kierkegaard
