Quotation from Samuel Johnson; No. 126 in The Rambler, 19 January 1754.
The full letter can be found here.
Piety practised in solitude, like the flower that blooms in the desert, may give its fragrance to the Winds of Heaven, and delight those unbodied spirits that survey the works of God and the actions of men. But it bestows no assistance upon Earth by beings [earthly beings], and however free from taints of impurity, yet wants the sacred splendour of Beneficence.
January 19, 1754
