The significance of that ‘absolute commandment’, know thyself — whether we look at it in itself or under the historical circumstances of its first utterance — is not to promote mere self-knowledge in respect of the particular capacities, character, propensities, and foibles of the single self. The knowledge it commands means that of man’s genuine reality — of what is essentially and ultimately true and real — of spirit as the true and essential being.
The man whom philosophy leaves cold, and the man whom real faith does not illuminate, may be assured that the fault lies in them, not in knowledge and faith. The former is still an alien to philosophy, the latter an alien to faith.
The heart is everywhere, and each part of the organism is only the specialized force of the heart itself.
A philosophy without heart and a faith without intellect are abstractions from the true life of knowledge and faith.
