Philosophy seems less interesting to me nowadays because I am upset about what is going on in the USA and I do not see philosophy as ever getting issues of government correct.
For some reason Plato, Kant, Leonard Nelson, Hegel may have been great and deep thinkers, but when it comes to political issues they did not seem to have that same degree of insight or talent.
The people that got politics right the founding fathers of the USA Constitution were not philosophers and they did not base their thought on philosophy. Rather they based their ideas on England and especially the Glorious Revolution of 1689.
It is not that the issues were all that different. Rather that the philosophers got the issues wrong. Hegel saw the terrible mess of the French Revolution but his solution seems to involve too much government. Kant also was dealing with the crisis of modernity of Germany after the old structures of society were changing. But his solutions also do not seem accurate--too much world government and or too much individual.
What ever Thomas Jefferson and James Madison got right, it was not based on philosophy.
