You talked in an earlier post* about economists' attitudes about mercantilism. Where do the physiocrats fit into this? What were they trying to do, what do current economists think of them, and how accurate is their assessment?

First of all, thank you for including the link! It really helps.
Ok, so let's talk about the physiocrats. This was a pre-Smithian school of economists from France in the 18th century, and they are somewhat complicated to assess because their ideas are a strange mix of surprisingly accurate and completely batshit:
unlike the mercantilists, who they really didn't get along with, the physiocrats thought that growth and especially the circulation of wealth (as opposed to achieving a positive balance of trade and deepening capital pools as the means of driving development) was the most important goal of economic policy.
unlike the mercantilists and the classical economists, the physiocrats believed in the labor theory of value...but only for agricultural labor. The reason they called themselves "physiocrats" is that they believed all wealth came from nature, and that all industrial and commercial and other forms of labor were "unproductive appendages" that existed parasitically off of agricultural labor. This is particularly insane, given that they were writing on the very eve of the Industrial Revolution but well after the Commercial Revolution, so they were well aware that European countries had been making increasingly large amounts of money from stuff that wasn't agriculture. This, they felt, was cheating.
in terms of policy prescriptions, the physiocrats' main agenda items were free trade in grain - they firmly believed that any form of government intervention (say, during a famine to prevent starvation and bread riots) was inherently counterproductive and an unwarranted inference in the natural right of producers to maximize profits, which would eventually lead to higher production and lower prices - and a flat tax on property.
This school of thought was initially quite influential duiring the early stages of the French Revolution, but broke down almost immediately when there was a bad harvest and food prices shot up through the roof, because when large numbers of starving people who have just gone through a revolution and now have weapons and believe they have a right to use them to defend their lives and their freedom see the rational self-interest of grain merchants jacking up the price of their daily staple by 400%, they respond by killing them and putting their heads on pikes and taking the food by force. In that scenario, any government is going to react through intervention if only out of their own rational self-interest. Hell even the ancien régime knew enough to do that, and now the government is run by a bunch of Jacobins.
I would describe their reputation among contemporary economists as one of outwardly-polite condescension of the "well, bless your heart" school of southern gentility. They did hit on some ideas that later economists would run with, but at the end of the day they aren't Big Daddy Adam Smith so they are a mere footnote. But then again, contemporary economists are surprisingly ignorant about the history of economic thought, so it's to be expected.
