Ludwig Feuerbach,
The Essence of Christianity — Chapter XXVII
(1841)
“ Think, therefore, with every morsel of bread which relieves thee from the pain of hunger, with every draught of wine which cheers thy heart, of the God, who confers these beneficent gifts upon thee,—think of Man! But in thy gratitude towards man forget not gratitude towards holy Nature! Forget not that wine is the blood of plants, and flour the flesh of plants, which are sacrificed for thy well-being! Forget not that the plant typifies to thee the essence of Nature, which lovingly surrenders itself for thy enjoyment! ”
