Spectra of lighter nuclei can often be interpreted via the bosonic degrees of freedom formed by the strongly bound alpha particles in contradiction of the fermionic degrees of freedom given by the nucleons in such nuclei. I will review the present situation of the possibility of alpha particle condensation in self conjugate nuclei with possible extensions to other non-selfconjugate ones. A short round up of quartet condensation in infinite matter in opposition to the well known pair condensation will also be given.
