The multitude requires no laws to coerce those who think not like itself: public disapprobation is enough; a sense of their loneliness and impotence overtakes them and drives them to despair.
Whenever social conditions are equal, public opinion presses with enormous weight upon the mind of each individual; it surrounds, directs, and oppresses him

Context

“when they find themselves at variance with the greater number of their fellow-countrymen, they withdraw to their own circle, where they support and console themselves. Such is not the case in a democratic country; there public favor seems as necessary as the air we breathe, and to live at variance with the multitude is, as it were, not to live. The multitude requires no laws to coerce those who think not like itself: public disapprobation is enough; a sense of their loneliness and impotence overtakes them and drives them to despair. Whenever social conditions are equal, public opinion presses with enormous weight upon the mind of each individual; it surrounds, directs, and oppresses him; and this arises from the very constitution of society, much more than from its political laws. As men grow more alike, each man feels himself weaker in regard to all the rest; as he discerns nothing by which he is considerably raised above them, or distinguished from them, he mistrusts himself as soon as they assail him.” source
