The presumptuous judgement of the ignorant upon their designs

From An account of the European Settlements in America by Edmund Burke.

There is a sort of enthusiasm in all projectors, absolutely necessary for their affairs, which makes them proof against the most fatiguing delays, the most mortifying disappointments, the most shocking insults; and, what is severer than all, the presumptuous judgement of the ignorant upon their designs.

Sounds like a much kinder description of those who, by Thomas Sowell's description, have The Vision of the Anointed, cruelly, though accurately, sub-titled, Self-Congratulation as a Basis for Social Policy.
