"This buckling down to the task of furthering the true as against the false in the big and little affairs of everyday, although it is not highly regarded by the devotee of absolute and abstract Truth, happens to be the kind of truth-concern upon which progress in the attainment of truer beliefs, attitudes, and ideas depends. Truth from this point of view is a collective name for a sum of particular truths, as true as they are and no truer. Since the scientific humanist consistently endeavors to improve the standard of the true precisely where there is greatest need that this be done, it should be obvious that truth has a place of unusual honor in scientific humanism."

1. What does "the kind of truth-concern" mean in the context?

2. What does the author mean by "as true as they are and no truer" and by the blue clause?

Please help me!

Thank you
