SIR – Julian Thake says I shan’t “wriggle out” of questions on abortion which I leave unanswered (November 25).

The fact is, I don’t pretend to have all the answers. I don’t imagine that I have privileged access to moral truth.

But you don’t always have to know exactly where a line in the sand should go to know that someone else has put it in the wrong place.

I do think that the current time limitations on abortion are a good working compromise.

But what do I know?

Andrew Grant, however, apparently thinks that even in the most dire of circumstances, and even in the earliest stages of pregnancy, abortion is wrong.

Difficult as knowing where to draw the line is, the idea that we should have to hold an embryo inviolate at these earliest stages is tantamount to saying that we are under an obligation to maximise human fecundity wherever possible. A nightmare scenario.
