The "present age" is a concept in the philosophy of Søren Kierkegaard. A formulation of the modern age can be found in Kierkegaard's work Two Ages: A Literary Review:
Our age is essentially one of understanding and reflection, without passion, momentarily bursting into enthusiasm, and shrewdly relapsing into repose. ... There is no more action or decision in our day than there is perilous delight in swimming in shallow waters.
— Kierkegaard, Søren, Two Ages: A Literary Review.[1]
