'I have been accustomed to call this book, I think not inappropriately, "An Anatomy of all the Parts of the Soul;" for there is not an emotion of which any one can be conscious that is not here represented as in a mirror. Or rather, the Holy Spirit has here drawn to the life all the griefs, sorrows, fears, doubts, hopes, cares, perplexities, in short, all the distracting emotions with which the minds of men are wont to be agitated.'
John Calvin, Commentary on the Book of Psalms, xxxvii.
