(1817 - 1881)
Lotze was a German Idealist, as well as a logician, and metaphysician.
He studied at Leipzig, and at the tender age of 27 became a professor at Gottingen, where he remained until near his death, when he went back to Berlin for a chair.
His project, insofar as each philosopher can be said to have one was to try and combine idealism with empiricism, or at the very least to remove some of the antagonism that had existed between them since the time of Hume. Checkout Hume's Induction Principle for a notion of what I'm talking about, or even Hume's Law.
In any case he did this by using an idealistic base, and tempering it with empiricism, which seems reasonable enough. However, he then proceded to find intelligibility possible only through the relationship between spirits and the Almighty God.
While this may seem odd to us now, it was part of a wider philosophic movement, called panpsychism which tried to use the notions of God to untie some of the basic philosophical knots of the day.
His principle works were:
Logik (1874),
Metaphysik (1879)
