every worker, in all spheres, is a worker not on semblance but on substance

Context

“Every son of Adam can become a sincere man, an original man, in this sense; no mortal is doomed to be an insincere man. Whole ages, what we call ages of Faith, are original; all men in them, or the most of men in them, sincere. These are the great and fruitful ages: every worker, in all spheres, is a worker not on semblance but on substance; every work issues in a result: the general sum of such work is great; for all of it, as genuine, tends towards one goal; all of it is additive, none of it subtractive. There is true union, true kingship, loyalty, all true and blessed things, so far as the poor Earth can produce blessedness for men.” source
