 To begin, Thomas (1987; 1989; 1993; 2013) claims that we should understand what is here called the intimacy of friendship in terms of mutual self-disclosure: I tell my friends things about myself that I would not dream of telling others, and I expect them to make me privy to intimate details of their lives. The point of such mutual self-disclosure, Thomas argues, is to create the “bond of trust” essential to friendship, for through such self-disclosure we simultaneously make ourselves vulnerable to each other and acknowledge the goodwill the other has for us. Such a bond of trust is what institutes the kind of intimacy characteristic of friendship. (Similar ideas can be found in Annis 1987.)
