(That's over 50 years folks).

Pluswhich, I contend that: without some sort of faith (in something), some sense of adventure and/or an actual *interest* in what these theories (seem to) imply about "reality" -- there would be no further progress (or theories even). People would just sit around and wait for research data, rather than stepping out on a limb with scientific speculation. It is *ideas* (theories, guesses, interpretations, conjecture, etc.) which provide impetus and direction (i.e., what intelligent questions to ask next). Also, these theories give other scientists ideas... stuff to ponder, expand, and/or debate [i.e., what does it mean?].


From here I need to examine the language.

Encarta® World English Dictionary

Belief, is an acceptance

Faith, is a simple word that has meaning beyond simple "confidence".

Confidence in ones self, environment, associates, process, study, direction, scope…and so on. Confidence comes with a trust element and trust can be earned. There is an element of risk in Confidence so there needs to be a value assessment.
