John Stuart Mill's essay 'On Liberty' is to me the greatest secular work on the subject of individual liberty ever written. I consider individual liberty to be the most important aspect of moden life.
Mill's essay starts like this:
| THE SUBJECT of this Essay is not the so-called Liberty of the Will, so unfortunately opposed to the misnamed doctrine of Philosophical Necessity; but Civil, or Social Liberty: the nature and limits of the power which can be legitimately exercised by society over the individual. A question seldom stated, and hardly ever discussed, in general terms, but which profoundly influences the practical controversies of the age by its latent presence, and is likely soon to make itself recognised as the vital question of the future. It is so far from being new, that, in a certain sense, it has divided mankind, almost from the remotest ages; but in the stage of progress into which the more civilized portions of the species have now entered, it presents itself under new conditions, and requires a different and more fundamental treatment. | 1 |
| The struggle between Liberty and Authority is the most conspicuous feature in the portions of history with which we are earliest familiar... |

Ayn Rand is probably the exact opposite of Marx (ideologically). I respect both thinkers a lot and I always consider their works as food for further thought rather than the last word on a subject. I disagree with a lot of Marx's and Rand's prescriptions for society but I cannot ignore them. I am in agreement with most of their descriptions of the inadequacies of society as we know it. I have very high regard for Marx as a foremost thinker who is probably the most influential intellectual legislator of the last century.
In September 1999, BBC News Online users voted for the greatest thinker of the last thousand years. They voted overwhelming for Karl Marx.
From the BBC Website.....
Marx the millennium's 'greatest thinker'
Karl Marx: Controversial revolutionary ideas
Revolutionary writer Karl Marx has topped a BBC News Online poll to find the greatest thinker of the millennium.
The nineteenth century writer won September's vote with a clear margin, pushing Albert Einstein, who had led for most of the month, into second place. The top 10 included philosophers Immanuel Kant and Rene Descartes as well as twentieth century scientist Stephen Hawking.

This is very insightful stuff. I agree about the importance of a person contributing something unique to humanity. But I would not call that the ‘purpose’ of that human being. I am careful not to use the word ‘purpose’ that way, I would rather call this a ‘life-mission’ or ‘life-work’ or even ‘life-contribution’. I prefer to use the word ‘calling’ but not in the limited dictionary definition you quoted.
For me ‘purpose’ for a human being must be linked to the reason for being created, the reason why you are alive, why are you a human ‘being’ rather than a human ‘doing’?
What is a human? The same answer should suffice for every human being…this is ‘purpose’. The starting point to define ‘purpose’ should be ‘what does it mean to be a human being (regardless of your race, colour, age, education)?’
In my terrible analogy concerning an airport shuttle bus, the purpose of the airport shuttle bus is the same purpose for every bus of any size or shape all over the world: to transport things (be it people or objects).
For the airport shuttle bus to “…be here because no one else could bring what you can and so you are meant to contribute your uniqueness, your insight, yourself- to humanity…” would be for the bus to transform itself to a shuttle bus and fulfilling its mission on Earth ! But it would still be fundamentally a bus, purpose unchanged.
In summary: purpose is the same for every human being, but life-work/life-mission will differ. In fact a person can be created for 2 or even 3 ‘callings’ in one life-time but his/her purpose (reason for ‘being’) is never changing and remains only one.
