Sven-S. Porst challenged me to talk about email encryption (PGP/ S/MIME, or something), and to suggest to 5 others that they do the same… I realize that you aren’t all Mac folk, but it’s reasonably straightforward in Thunderbird, Outlook, Evolution, and several other mailers, so hopefully you’ll give it a whirl.
In respect to lock-making, there can scarcely be such a thing as dishonesty
of intention: the inventor produces a lock which he honestly thinks will
possess such and such qualities; and he declares his belief to the world.
If others differ from him in opinion concerning those qualities, it is open
to them to say so; and the discussion, truthfully conducted, must lead to
public advantage: the discussion stimulates curiosity, and curiosity stimu-
lates invention. Nothing but a partial and limited view of the question
could lead to the opinion that harm can result: if there be harm, it will be
much more than counterbalanced by good.”

published around 1850.
