If there's one thing i have learned with Jung's theory of brain functions, it's that we all think differently. Descartes was wrong. Without outside stimuli, we wouldn't perceive much, but we would judge, and that judgments would be somewhere on the subjective(F)/objective(T) scale, different from person to person.
Ultimately, the ironic thing is, the more objective a person tries to become, the more intolerant of opposing systems they become. It is the T that has his own beliefs and treats everything else as mere amusements, where the F being subjective and creating his own belief system, is very understanding of opposing beliefs. In a sense, because people are subjective, they appreciate others who act the same way.
Ts understand things by pulling them apart and understanding their individual objects. Fs understand things by putting things together and understanding how they work as a whole.
For example, Scientists are usually Ts, philosophers, F.
Perhaps then, that is why Scientists have such a hard time accepting religion. Religion is a whole belief system, where each individual part (usually) only makes sense within the whole. Each part may have a distinct function, but the function is useless without the system. Science, however, is understood in individual parts, and it takes a theory to bring it together. It is the theory that makes no sense without the individual parts. The parts themselves stand on their own.
To take that further, if in Science the individual parts (findings) disagree with the whole (theory), the theory is rewritten. If in Religion the individual parts (understandings) disagree with the whole (belief), the findings are understood differently.
With Scientists being Ts, they are in the relentless pursuit of objectivity. The downside is their tendency to be derisive towards anything subjective. Religionists are generally more accepting of Science (where it does not conflict with their beliefs), and can appreciate other belief-systems even if they condemn them. The downside is their tendency to be afraid of being objective where the religion does not have a(n existing) belief.
If religionists need to be more open-minded to objectivity, Scientists need to be more understanding of subjectivity. We are all a mixture of both qualities, and merely sticking to our preferences limits our growth severely.
