David Cameron yesterday launched a beefed up version of his flagship "mission statement" after activists raised concerns about a lack of detailed policy.
The Conservative leader said the revised version of the Built to Last document would allow the party to set a "new direction" for Britain.
He insisted it presented "quite a change" from the initial draft, which came in for criticism during a consultation with the Tory rank and file.
S pecific measures announced in the interim - such as controversial plans for a "Bill of Rights" - have been included.
However, there are no pledges for tax cuts, which had been called for by many members.
The final 12-page version is twice as long as before, and sets out a message of "change, optimism and hope", according to Mr Cameron.
In the foreword, he calls for a "responsibility revolution": "The country needs a new direction and new answers. I am clear about the new direction we must set for Britain.
"To meet the challenges of the 21st century, and to satisfy people's aspirations today, this country needs a responsibility revolution."
Mr Cameron wrote that individuals, communities and businesses should be given the skills, resources, freedom and incentives to act responsibly.
He added: "That is the mission of the modern Conservative Party: a responsibility revolution to create an opportunity society - a society in which everybody is a somebody, a doer not a done-for.
"Ours is a message of change, optimism and hope. Our aims and values are built to last; they are as relevant now as they have ever been."
All party members will be given the chance to vote on the new document over the next month, and Mr Cameron has said he is hoping for a "thumping majority".
It is believed he hopes to emulate Tony Blair's 'clause IV moment' - modifying public perceptions of the party by winning a symbolic victory over reactionary elements.
Results of the consultation with activists on the original document were published on Tuesday.
Despite the party's resurgence in opinion polls, the findings showed a degree of discomfort over Mr Cameron's perceived lack of detailed policy - a criticism often levelled since he took over as leader.
An official summary of the views revealed members had asked why there were no explicit commitments on pensions, why it ignored science and technology, transport and housing, and why there was no mention of "Britain as a player in European and global politics".
Concern over efforts to boost the number of women MPs through the controversial A-list of candidates was clear, with the summary concluding: "Members reasoned that the party should be meritocratic, not tokenistic. Meritocracy is more important than quotas."
There were also reservations over Mr Cameron's emphasis on Green policies: "While it is right to give prominence to issues such as the environment and global poverty, these should always be complemented by other issues."
But yesterday's final document shows no sign of backing away from the Tory leader's high-profile environmental agenda, or his emphasis on tackling global poverty.
Defending the original draft of the mission statement, Mr Cameron said party activists had "liked" the aims and values, but wanted to know more detail.
He said the updated document gave a "sense of direction" for what a Conservative government would actually do.
The document sets out dozens of policy aims in eight areas, such as encouraging enterprise, fighting social injustice, meeting environ-mental threats, and improving public services. No new measures are disclosed.
Among the most specific commitments are a "unified border police" and a homeland security minister, introducing a Bill of Rights to replace the Human Rights Act, and scrapping the Government's proposed ID card scheme and unelected regional assemblies.
There is also backing for "flatter and simpler" taxes, and more schools streaming and setting.
