“Science is the language of the Temporal world, Love is that of the Spiritual world.”
Source: Seraphita (1835), Ch. 3: Seraphita - Seraphitus.
Context: Science is the language of the Temporal world, Love is that of the Spiritual world. Thus man takes note of more than he is able to explain, while the Angelic Spirit sees and comprehends. Science depresses man; Love exalts the Angel. Science is still seeking, Love has found. Man judges Nature according to his own relations to her; the Angelic Spirit judges it in its relation to Heaven. In short, all things have a voice for the Spirit.

“I inaugurate through science
The hymn of all hearts spiritual”
"Prose" (1885).
Observations
Context: Hyperbole! can you not rise
In triumph from my memory,
A modern magic spell devise
As from an ironbound grammary:
For I inaugurate through science
The hymn of all hearts spiritual
In the labor of my patience,
Atlas, herbal, ritual.

The Practice of Psychotherapy, p. 364 (1953)

“Science depends on outer experiment. Spirituality depends on inner searching and seeking.”
Songs of the Soul (1971)
Context: Science depends on outer experiment. Spirituality depends on inner searching and seeking. A scientist discovers the power that very often threatens even his own life. A spiritual seeker discovers the power that guides and moulds his life into a life of divine fulfilment.
