Ok guys, everyone is entitled to their own views, and may rejoice in flaunting the flag for Mer in their own natal-chart's sign the highest.
Why not see what established astrologers and authors (not blowing the trumpet for their own Merc
) have to say about Mer in Aries and Aquarius, since these two signs seem to be most in discussion on this thread. Kevin Burk, in his book:
Understanding the birth chart, says for Mer in Aries:
"Aries energy is too focused on expressing individual identity to even think about exploring anything else. Mercury in Aries becomes very limited by this energy: as fascinating a subject as each of us is, we're not really the centre of the universe! Mercury needs more freedom to explore, and with more objectivity than Aries allows it.. The biggest challenge for Mercury in Aries is the tendency to start talking before engaging the brain.. Mercury can often find that it has asserted itself into a corner and wound up in an argument that it can neither win nor concede without losing face"
For Mercury in Aquarius, Burk says: "
Aquarius is ..Saturn-ruled and concerned with structures and responsibilities; but Aquarius takes a much broader and more abstract point of view- our place in society -and this gives Mercury a bit more to work with. Mercury in Aquarius is free to express a much broader range of ideas, although overall it will tend to be attracted to personal freedom and social dynamics. As with Libra, in a night chart Mercury is able to function quite well- it is able to latch onto the objective (if somewhat idealistic) energy of Aquarius, and express itself quite comfortably. "
Re emotions and humanitarianism, I feel that not feeling that comfortable with relating on very close, one-to-one (Aqua is a group sign where the 'personal' ego & identity get dissolved into the 'we' energy) emotional terms is not, per se, the equivalent of "lack of insight into human emotions". On the contrary, it is this very emotional detachment of a 'one-to-one' basis that makes this sign so humanitarian (a collective term) and mankind- (another collective & group term) oriented, as it is able to look at the 'bigger (collective) picture' more objectively- without letting emotions cloud the mind. Conversely, being overtly emotional on a one-to-one basis or too emotionally attached also doesn't make one, per se, very 'genuinely' humanitarian.
As I said earlier, Mercury performs its role in every sign the best it can, but under the influence of different energies (as per the its sign-placement). However, the energy that suits it the best is one which supports its ability to rationalise, analyse and communicate (its main roles and purposes) the most congenially, so the element of water might not be that well-suited for this purpose. Nonetheless, even in water signs, Mercury has some dignity by term/face.
