Introverted Sensing often plays an important role in the private world of the INTP.
When he visits a place, whether new or already known, his Si function gives an
overriding concern for the atmosphere or mood of the place. In his subconscious,
he connects the present experiences of his surroundings with memories of his past,
sometimes deep past. A sense of history, of universality, is almost always invoked.
When on holiday, the INTP wants to experience above all the ambience of each
location. Specific details in the present are relatively unimportant and will not be well
remembered. However, the atmosphere or mood will be remembered long after, as
though it were a solid object. Since people encountered on a holiday usually count
as details, unless more personal contact develops, the INTP tends to be drawn more
to lonely, isolated places where atmosphere is less disturbed. Nevertheless, the
presence of people does add its own ambience which can also be appreciated considerably. The net result of this concern for past experiences and of mood/atmosphere is that INTPs belong centrally to those types referred to as melancolic. The INTP melancolic is typically drawn to wild polar expanses, to mountain ranges and all places on the edges of civilisation. Whatever his particular yearning might actually be, it has a common root. The homeland of the INTP's
psyche is a small and cosy community, isolated in the middle of a vast expanse of
wilderness.
Because the present is inextricably linked to a sense of the past, INTPs tend to
hoard items which help solidify the connection to the past. They find it very difficult
to let go of anything they have collected (or indeed created) and which may have a
nostalgic meaning. They assume that any object which is of interest now is bound to
remain of interest for the rest of their lives. This emphasizes a strong sense of
universality in the progression of time, just as it emphasizes the seriousness with
which INTPs approach their interests. Frivolity is not in their vocabulary. INTPs often
love keeping lists and databases in areas of interest, especially when the lists are
associated with things of the past. Collecting periodical magazines or other media of
interest is also a very common INTP trait. Such a collection is usually taken very
seriously. Yet the collective whole, considered as a temporal rather than spatial
object, always assumes more importance in the mind of the INTP than the objects
forming the collection themselves. Hence, INTPs are collectors, but they are
collecters for whom the objects themselves are only important in so far as they
evoke a connection to past events, in so far as they yield a nostalgic mood. The
curious problem with any collection of an INTP is that he typically fails to enjoy it in the here and now. Items are stored away so that they can evoke this time at some
point in the future, but such a point often never occurs. It may never occur because
INTPs are always so mentally active that they continually delve into new interests,
and continue to hoard items relating to these, so that they rarely allow themselves
enough time to reflect on the ever expanding library of their past. The interests of an
INTP would be enough to occupy him for several lifetimes if that were possible.
