The challenges we face are daunting, but in Go Big Ed Miliband shows that the scale of what is possible is far greater. The ruling class achieves this through the state, with laws to constrain trade union activity, police repression of strikes, and surveillance of those who seek political change.

Sadly the warm embrace of Miliband by sections of the Corbyn movement was not the generosity shown to a prodigal son, but a dangerous meeting of minds in a soup of political confusion. This threat can only be resolved by the emancipation of humanity from class society, which involves emancipation from the state. Maybe they’ve all been listening to his Reasons to Be Cheerful podcasts – and now they can riffle through Go Big and nick Miliband’s ideas on “how to fix our world”. If the politics of the past five years, or the past 50 years, has taught us anything, it might perhaps be that the wisdom of Dr Pangloss only gets you so far.

It has this incredibly compelling character at the centre of it, Billy Beane, who picks players – and maybe this says something about where my sympathies lie – who are ‘flawed’, which means the market undervalues them. His desire is explicitly to reduce class conflict and reconcile our class with those who exploit us. However, I found it frustrating that every chapter had a vague title so you can't easily refer back to the book to look at one of the many different ideas that Miliband discusses. Some will be reinvested in overhead costs like electricity or repairs, but the rest will be allocated to owners and investors in the form of profit.

The book is clearly political in the most basic sense – it looks exclusively at socioeconomic problems and offers “big” solutions. Given that employee-owned businesses including sole trades currently contribute around 2-4% of GDP, this is really meagre stuff; not least when one bears in mind the scale and urgency of the climate emergency facing us – an issue which is supposed to be Miliband’s strong suit.After all, wasn’t the Corbynite policy platform quite timid when it came to public ownership, let alone workers’ control of industry? You can only trust that President Xi of China and comrade Putin, not to mention our own Brexity prime minister, have received advanced copies of his book.

When Mr Miliband points out in the Commons that the Tories have appropriated his ideas without the size of his ambition, cabinet ministers chuckle that “we are all revolutionaries now”. This study maps the ideas - old and new - that were debated and adopted by the Labour Party under Miliband and shows how they were transformed into policy proposals and adapted to contemporary circumstances. Non of Ed's solutions are particularly radical in my mind - he cites numerous examples of how they have been successfully adopted elsewhere. We do care about each other, we do have a deep well of empathy…” That “we” becomes so insistent in the course of his book that you start to wonder who he means by it – all of his likely readers?

The answers, she argues, lie in choosing determination over hope, and having faith in our fellow humans.
