Chastity

"Only chastity is linked to personal progress".
[Camus, notebooks]

1.
I think here of 'chastity' in the widest sense;

'chastity', from the Latin 'castus', i.e., pure.

Sexuality is only 'impure' if one regards sex as 'dirty'.

2.
The word 'castus' is ultimately from the Indo-European root 'kes-', meaning 'to cut'. The original sense was to be 'cut-off, or free from faults'.

What then are our faults?
