Context

“when we have carried our investigation further it will appear to us in a still less favourable light. Dogmas change and our knowledge is deceptive; but Nature never errs, her procedure is sure, and she never conceals it. Everything is entirely in Nature, and Nature is entire in everything. She has her centre in every brute. It has surely found its way into existence, and it will surely find its way out of it. In the meantime it lives, fearless and without care, in the presence of annihilation, supported by the consciousness that it is Nature herself, and imperishable as she is.” source
