Aristotle believed that abortion was permissible 'before sense and life have begun,' so it should take place before there are any signs of an individual human having been established. However, there is much debate on the point at which a foetus becomes an actual person, with some people arguing that it becomes a person birth, or when all its features have developed, or when it's brain has developed, and some argue that it becomes an individual person at the point of conception, in which case it cannot be permissible by Aristotle's virtue ethics, as murder is what Aristotle called a 'base act,' meaning that it can never be morally good because there is no way of committing murder rightly or wrongly, so it is a bad act in itself. However, virtue ethicist Rosalind Hursthouse argues that as we do not know enough about the biological facts to know about the status of a foetus, the decision is up to the woman, as a virtuous woman has the character traits of strength, independence, confidence and responsibility to make her own decision
